Home / I-Opener Areas / I-Opener Technical Stuff LoadBios A Bios Loader

LoadBios (modified 0 times) Programmer Profile at http://bethie.net/~programmer/loadbios.com is a program that will load (from dos) a new bios without flashing the existing bios. The BIOS image to be loaded must be named BIOS.IMG and must be in the current directory. This should be useful for testing new bioses; to get your original bios back after using, turn off then back on. changes you make to bios settings while using this program will likely remain changed. I have not tested this extensively, so you are at your risk (though I will guarantee that it doesn't write anything to the bios) 01-22-2001 08:29:17

RE:LoadBios (modified 0 times) mp3boombox Profile | Email If that is the case then can you save the settings with that program? if so you could share your FIXED irq bios with the rest of us. I'm having problems locating the program which saves the cmos to disk. to reload it into a bios if settings have been lost. i'll do some more searching tonight. 01-22-2001 15:07:43

RE:LoadBios (modified 0 times) Programmer Profile no this won't save anything to disk. 01-23-2001 06:52:20

RE:LoadBios (modified 0 times) Programmer Profile Don't use this program.. it won't hurt anything, but it won't work either, thanks to differences in various chipsets, it sets stuff up wrong.. anyone ever get a datasheet for the Via 8501?? 01-23-2001 08:07:58

RE:LoadBios (modified 0 times) Programmer Profile Hey Hey.. I found the datasheet and (hopefully) fixed everything up.. if someone has an IO and an obviously different bios image, please give this a try, it won't hurt your IO and should be very useful for testing changes to the bios (new startup pictures, wild pencils cdrom fix, etc) 01-23-2001 10:08:45

RE:LoadBios (modified 0 times) asm_ Profile Programmer, I have found the program that will save the BIOS setting to a file. Here is the link. http://brian.atg1.com/pub/biosutil.zip Can you kindly share your BIOS setting with the rest of us? PS. if it's possible, can you also indicate the version number of the IO which the BIOS setting is extracted from? thanks 02-24-2001 00:32:51

RE:LoadBios (modified 0 times) Wild_Pencil Profile | Email Programmer, Are there any special settings or requirements for LoadBIOS? I've tried it a few times, and I get inconsistent results -- almost always a screen full of text-garbage as if the VGA wasn't initialized or something... This application would be a huge help in my BIOS efforts -- flashing new (broken) BIOS images and then reverting to a known-good BIOS chip consumes a lot of develoment time.. -WP 02-27-2001 16:18:43

RE:LoadBios (modified 0 times) Programmer Profile OK I went and looked, and the reason it doesn't work is that it's loading the award rom into place, and it tries to decompress to shadow, which doesn't work because it's IN shadow. http://bethie.net/~programmer/loadsegs.zip has a few files in it which should help.. loadef.com will put the 128K ef.img file (which should be the uncompressed 'REAL' bios) into the proper place in memory and make it ready to be jumped to. loadD.com will put a 64K d.img file (be careful here because there are normally 4 separate 16K roms here) into the memory at D0000, should be useful for testing your OEM roms loadC.com is basically the same thing as loadD.com, but puts the data into C0000 reboot.com, does a warm boot by jumping to FFFF0 the source is included, and if you need to load something to a different address it should be fairly easy to do, or let me know and I'll do it.. the C0000 - FFFFF address range is the only range that can be put into a protective shadow. I haven't spent any time to look where Award decompresses the boot image to.. 02-28-2001 09:04:26
