Home / Web Pads / Panasonic CF-01 8-Bit / 256 Colors working with 40 meg mem CF-01 Custom Video with SciTech

8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) pete Profile I was able to get true 8-bit video with 40 meg upgrade working tonight with SciTech Video Dr. Think with some more tweaking 16-bit is possible. It appears that Window Panasonic driver is a non standard customized video driver for Windows 95. On Chips & Tech site there are tools to create custom Windows drivers if any one is interested. 05-03-2001 22:22:03

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) tcbordp Profile Great work Pete. The video, suspend and hibernation were the only issues I saw with the 32m upgrade and I have come to the conclusion that the hibernation problem was from the FAT32 partition. Have you tried normal suspend with the 40M installed and does it work correctly? PeteB 05-04-2001 00:53:06

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) pete Profile Normal suspend works. Now thinking of putting in a spare 6.4 gig. Is the HD plugged in at one end? I have taken the HD cover off...what's the procedure to pull the drive out? How much slower is 98 SE? 05-04-2001 05:23:16

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) ubik Profile 1) remove the battery cover 2) remove the hard drive cover 3) remove the screw in the middle of the case back 4) pull out the drive I replaced my drive with a 6Gig, and used double-sided foam tape as spacers to align the HD in the case. Otherwise the connectors wouldn't mate correctly. The rubber spacer under the HD cover keeps everything tight so you don't need to use the screw in the case back. 05-04-2001 12:12:33

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) pete Profile Just got 16-bit video working. No lockups. Works great. Validated 16 bit color with Polyview. 05-04-2001 16:16:42

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) tcbordp Profile Really great, of course that adds another $40 to the price of the ram upgrade. I am running win98se on mine but I installed using 98lite and chubby mode (little html integration / no active desktop) and it works pretty good even with the 24m. I will have to give my 32m upgrade and the scitech driver a try. Did you have to do anything special to get the driver to work? Details appreciated. PeteB 05-04-2001 16:20:59

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) pete Profile Yes I do ....set the driver to use a 65540 instead of a 65548. Email me for a special fix. 05-04-2001 19:22:36

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) tcbordp Profile Pete: Don't know your email but if you would send me the details at pw.borders@verizon.net. PeteB 05-04-2001 19:44:28

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) JunkLeo Profile Try this tip from http://developer.intel.com/support/graphics/mobile/16colors.htm CHIPS Graphics Controllers Display only shows 16 colors when running Windows* 98 Occasionally Windows* 98 can install in such a state where Windows 98 will only display in 60 color mode. This happens more often with our older parts such as the 65545. It also happens if the part is based on VL-BUS. To get around this issue, we have found that installing the Win98 VGA driver first and then installing the Chips & Technologies video driver afterwards will get rid of this issue and allow Win98 to display in 256, 65536 and 16million color modes (if they were originally available on your notebook) How to install the VGA driver under Win98: From the start menu, select settings and then control panel. Select the display icon. Select 'settings' and then click on the 'advanced settings" button. Click on the 'adapter' tab and click on the 'change' button. Select next and select the choice that says "Display a list of all the drivers...". It is the 2nd radio button. Click on the 'Show all hardware' radio button. In the Manufacturer column, select '(Standard Display Types)' In the Models column, select 'Standard Display Adapter VGA' Win98 will display a warning saying that the VGA driver is not the correct driver for your system. This is normal. Select next. Select finish and Win98 will want to reboot the machine. After WIn98 reboots, install the Chips and Technologies display driver. 05-04-2001 21:09:08

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) pete Profile Think I had originally tried this and it didn't work. Did anyone else try it? I have 16-Bit color working currently with 40 megs internal and using SCITECH drivers. But if it would work this way then I would not need to use the SCITECH drivers. 05-05-2001 08:26:08

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) tcbordp Profile The problem with the video and memory upgrade is not a win98 problem. I originally put the memory upgrade in the original win95 install and had the exact same problem. I think that the video bios has mapped a frame buffer for video memory too low so it overlaps with real memory when you upgrade to 40M. That would also explain how the scitech driver can overcome this since it basically circumvents the original video bios and uses it own pseudo bios. PeteB 05-05-2001 20:34:41

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) tcbordp Profile Ok I will admit to being stuck. I am having no luck with the scitech driver. It keeps blowing up with various register contents displayed. It also quite often won't activate or gives me the windows display settings error on a reboot. Luckily I am not the only one with problems so I am posting this. Pete, could you give a detailed rundown on what you did to get the scitech driver to work? Is this under win95 or later? Did you configure it under plain dos first or what? Inquiring minds want to know. Related to that doesn anyone know if this screen can actually display 16 bit color. I thought DSTN couldn't go that high. You usually see specs for DSTN with 4096 colors or something like that. I guess it would be hard to tell for sure since the driver can claim to be in 16 bit mode but that doesn't mean the lcd has to display it. After all I can plug my monochrome vga monitor into my 24 bit color desktop and it doesn't suddenly display color. PeteB 05-12-2001 17:22:37

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) JunkLeo Profile Just made 16-bit colors work with 40MB. As Pete the Great said, select 65540 instead of 65548 in SciTech Display Doctor(I missed that post and tried a lot of things for two days for nothing). The procedure to upgrade to 40MB as the following: 1. change the display driver to Chips & Tech Super VGA, so CF-01 won't crash after adding memory 2. add 32 MB RAM 3. install SciTech DD, and select Chips & Tech 65540 which will set the frame buffer to 56 MB 4. enable SciTech DD driver 5. go to windows Display Properties->Settings->Addvanced->Adapter, if the Adapter Type is not SciTech DD, change it SciTech DD 6. go back to Properties->Settings and set Colors to 16-bit Thanks to Pete again.

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) JunkLeo Profile BTW using WVIDUTIL.EXE from http://www.intel.com/support/graphics/mobile/chip_id.htm clearly states the 1 MB video memory installed @1800000h (=24MB) on CF-01. It is the reason CF-01 crashes after adding more memory. Since we can't upgrade the CF-01 bios and video card bios(if any), SDD is the only way to go for now. Leo 05-13-2001 00:45:52

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) Groch Profile | Email JunkLeo, Thanks for the input. I still can't get it to work. I am using WinLite 98SE, (what operating system are you using) when installing as you describe I get some real weird flashes, usually a blue screen, and then scitech is not activated and I get a windows message on how my display driver is set wrongly. I cannot get it to load even on reboot. I am using all the auto settings except choosing the 40 chipset as you suggest. Do you have any of the options checked, or any ideas? 05-13-2001 07:06:43

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) JunkLeo Profile Groch, I still use the original windows 95, I had the same problems before manually select the SciTech DD driver in Display Properties. The steps I used after Windows failed every times: 1. Switch to the Chips & Tech Super VGA, 256 colors, reboot. Now it won't crash or complain when boots up. 2. Run SciTech DD control center, select Chips & Tech 65540 and auto-detect other settings. turn on SciTech DD driver in control center. OK and reboot. 3. After reboot SciTech DD control center indicates SciTech DD is running but SciTech DD driver is off for my case. 4. Turn it on again, and go to Display Properties->Settings->Addvanced->Adapter select Show all devices, then select SciTech Software, Inc./SciTech Display Doctor 6.53. Windows will try to install the dlls and ask the location of sdd9x.drv, set it to c:\sdd(or whatever you installed it to), reboot. Hope it will work for you. I was so frustrated when it didn't work and thought I wasted $49 on 32MB(Coast is 5 miles away, have to pay tax :(), now I feel great with my 40MB CF-01. Leo 05-13-2001 09:03:53

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) Groch Profile | Email Still not working here. I would rather guess its a Windows 98 issue than blame it on my own incompetance. I sure installed and reinstalled enough times. It will load fine in 16 colors, anything over that gives an error message that the driver doesn't match the hardware. If anyone has been able to get this to work in Win98SE I'd like to hear. 05-13-2001 16:36:52

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) pete Profile I have been out of town last few days and was "forbidden" to use the internet or check my email.....I finally was able to get mine to work but it was kind of a hit or miss thing.....reason why I haven't looked at the settings....it's not that easily done...in that it goes right into the configuration mode. You can also configure the video in DOS. I have not upgraded to 98 and left the machine at 95. I could email the config file for SDD though if anyone wants it...(its optimized to work at 40 megs and 16-Bit colors)....write me at pcalleros@hotmail.com...on another note if you go to the Chips & Technology WEB site the tools are there to custom write drivers and to also to write to Video Bios.....I am content with the SDD drivers....just reading the properties of the Chips & Technology I see: Graphics Chip: Chips & Tech C&T 65540 LCD with 1 MB Ram DAC: Chips 6554/x643x0 Internal 24 bit DAC Clock Chip: Chips 6554/x643x0 Internal Clock Please write and I can send the config file... 05-13-2001 16:51:36

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) tcbordp Profile Groch: I was seeing the exact same sort of problems that you describe. I am also using win98se and 98lite IV. I doubt that it is 98lite but it may be win98(se) that has a problem with scitech's driver. I see that both Junkleo and Pete are still using win95 and it works for them. Oh well until I find a work around I can live with 256 colors. PeteB 05-13-2001 18:40:04

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) Stoney49 Profile | Email I finally got it to work also in win95. I think the one thing I did different on the 100th try was to change the display driver to the Standard display VGA driver and rebooting before attempting to install Display Doctor. Thanks everyone who posted for the info, Scott I thought I was wrong once but I was mistaken ;) 05-30-2001 17:04:00

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 1 times) mondox Profile Stoney49, Did you get it to work with a full 16M color or just 256. I have only had success with getting the unit to operate in 256 color mode only. 05-31-2001 07:05:49

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) tcbordp Profile Pete: (PeteC now I think, Identity crisis eh? ) Do you have a direct url to the chips and technologies driver development information. I looked around and couldn't find anything. It would be easy to make a config.sys "driver" that would reprogram the chip to a different address if I had the information. It works fine under linux and X windows once you set the correct memory base address. The problem with using the information in X is that the X source distribution is hugh and finding the needed info would probably be a pain. I may download it anyway and have a go, maybe the info is delineated by chipset. PeteB 05-31-2001 16:33:50

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) PeteC Profile <PeteB> Somehow lost Pete during the updates...PeteC is fine though...but now I'm two. give this link a try: http://www.asilant.com/swtools.htm not a Chips & Technology site but a vendor with their tools posted. It would be great if you could write us new drivers.... 05-31-2001 22:46:14

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) Groch Profile | Email Pete, your link is slightly off, its http://www.asiliant.com/swtools.htm . I think Asiliant is all that remains of the video development for C&T. I have held off on buying the Display Doctor Drivers because so far as I can tell no one has gotten them to work on Win98. The original drivers work great except for that darn memory mapping business when you up the CF-01 memory. We would all be much in awe if someone could remap the addresses to make them work. 06-01-2001 01:24:01

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) JunkLeo Profile I looked at the document, it seems possible to dump the video bios, modify the frame buffer address and create a .com program which will run in autoexec.bat. But where is the BMP program metioned in the document? Without BMP we cannot create the bios patch .com file. Leo 06-01-2001 12:50:20

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) tcbordp Profile Junkleo: That is exactly what I am looking at doing. I played around with it a little last night but I have to do more with the actual bios files. If you download one of their bios files it includes the bmp54x.exe program that is the configurator for the bios. I know that it is possible as this is exactly how X access the chip, by changing the linear frame buffer location to 3b00000 from 180000 (may be short a 0 there). Be sure and share any insights you have into this whole thing. Between the lot of us we should be able to overcome this issue. Pete 06-01-2001 13:49:55

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) JunkLeo Profile The file Pete just metioned is http://www.asiliant.com/bios/545vl275.exe Though SciTech Video Doctor works under Win95, the Pivot driver failed. The best way is to hack the video bios. I will give it a try tonight after work. Leo 06-01-2001 15:07:04

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) Stoney49 Profile | Email In response to the question of whether I got it working in 256 or 16 bit, It's working in 16 bit. I could tell the difference also because I have a photograph background. I am running windows 95 though and a 6 gig hard drive in 3, 2gig partitions. Scott I thought I was wrong once but I was mistaken ;) 06-01-2001 19:06:48

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) JunkLeo Profile I dumped the 40K video bios, load it to BMPLarge.exe, changed the frame buffer address to 40Mb, save it as exe file and run it in the autoexec.bat. Though wvidutil.exe reports the frame buffer @28000h, the window still crashed in 16-bit colors. :( 06-02-2001 01:09:52

RE:8-Bit / 256 Colors working with 40 meg mem CF-01 (modified 0 times) PeteC Profile I am bringing this thread back to life again as I was wondering if anyone was able to create a new Video Bios that would work with 40 megs and 16bit color. I went back to using the SCI-Tech driver as it still serves its purpose. Still alternate using the CF-01 and or the Epods as a portable around the house do all- HS controller, WEB tablet, wireless this and that.... 12-18-2001 21:34:58
