Home / I-Opener Areas / I-Opener Technical Info Reference (MODERATED) VIA Apollo MVP4 BIOS info... VIA Apollo MVP4 chipset info...

VIA Apollo MVP4 BIOS info... (modified 0 times) CrazyBee I went to VIA's site and looked up the chipset thats in the IO. Apparantly it can be used for either desktops or notebooks and the chipset includes all hardware required. The info provided by VIA only lists one mobo made by Quanta and its nowhere near what the IO has. http://www.viatech.com/products/prodmvp4.htm Maybe, find a single board PC that has the same chipset with a LCD out on it and see if that BIOS is a viable alternative? I have been looking for one to no avail as of yet. Seems most of the SBC's and 1/2 and full length CPU cards are made by a few companies with many sellers. Almost all have LCD support AND on-board ethernet support. I am wondering of one were to use that BIOS if the lack of the on-board ethernet would freak the chipset out, or, if that is purely activated via a driver and run off of the PCI bus. 04-06-2000 18:06:29

RE:VIA Apollo MVP4 BIOS info... (modified 0 times) RavTon Hey I thought this group was MODERATED! The I-Opener doesn't have the MVP4 chipset! It's a combination of the Trident CyberbladeI7 northbridge and VIA VT82C686A southbridge. The video controller is in the Cyberblade. Trident is at http://www.tridentmicro.com/html/Products_folder/portable/cyberblade_i7.htm Come on codeman. Let's moderate! 04-06-2000 18:40:00

RE:VIA Apollo MVP4 BIOS info... (modified 0 times) CrazyBee WHOOPS!!! I think I goofed!! I got my MVP4 info from a thread in this forum.. it was by duvell: > >ftpgod: > >The bios ID is listed in the first post of this thread. It looks like we have an >evaluation version and the nameing does not follow the convention you described. I did >go to the web page you referenced and I found the 5 digit prefix that identifies the >chipset used in the IO. > >2A6LI -- Via MVP4 VIA 601(Trident video on-chip)/686A (Modem on-chip, Sound on-chip) > >I did not see any specific BIOS listed that used this 5 digit prefix. That is where I garnered my information from and acted upon it. I guess I will find out. 04-06-2000 19:22:31

RE:VIA Apollo MVP4 BIOS info... (modified 0 times) duvell I stand corrected. The IOpener uses VIA VT82C686 + Trident CyberBlade. While the MVP4 is VIA VT82C686 + VT82C501. The two sets are very similar. The northbridge chips seem to contain the same functionality and the only difference being which trident video controller is included. I posted in another thread the results of a program that probed and returned BIOS information and it called out the VT82C01 chip when I probed the IO BIOS. In anycase I found a place that has PCs on a card and they have models with both of these chip sets. From a features standpoint it looks very much like an IO with all the features populated. The company is Advantech. The two cards I refer to are: PCA-6752F: VIA VT82C686 + Trident CyberBlade PCA-6752N: VIA MVP4 (VIA VT82C686 +VT82C501) They have a datasheet that covers both cards. They did have a BIOS available for the PCA-6752. Note the lack of a suffix (F or N). I do not know if that indicates the BIOS is common between them or what. --duvell 04-06-2000 23:41:46

RE:VIA Apollo MVP4 BIOS info... (modified 0 times) geekydad I checked out Duvell's post at Advantech. This card certainly looks similar in specs, except there is no mention of USB support. I did a search on PCA-6752 and bios with the following link as a result: http://support.advantech.com/cservice/download.nsf/d8cab09a7c57481e4825686b00308ffe/0cde25adb88a157d4825685400330bb0?OpenDocument This is the location of the bios file. It's an award bios. Please note the remarks: Remark : 1.Fixed clear password when clear CMOS. 2.Support 2VGA(VIA & Trident). I don't know how it could support both but that's what's implied. Who knows! Still waitng for mine! 04-07-2000 09:05:12

RE:VIA Apollo MVP4 BIOS info... (modified 0 times) Tinker+Boy I downloaded the bios form the website and flashed my I-Opener with it, but alas it is dead. An odd thing about it though is that the Message Light would come on with the power. I put the BIOS back into my BH6 to flash it the only problem is the first 13 blocks of Flash memory now come up not being able to flash. The other flash areas are fine just the first 13. I removed the Goo from my second IO to flash and put into the first(Broke the BIOS Socket in the process--Ouch), but I had the same problem with it. My only guess is that the BH6's socket pins are worn out from me putting the BIOS's in and out. Just to let you all know though the BIOS for the MVP4 chipset will not work at all. I get just a black screen and the IO telling me that I have mail when I don't. It doesn't appear to be the LCD as the hard drive doesn't get any farther than spinning up. Keep hacking. 04-28-2000 12:54:00

RE:VIA Apollo MVP4 BIOS info... (modified 0 times) duvell Tinker Boy: I tried the same thing you did back when I found the Advantech BIOS, and then realized why it did not work. There may be other causes but the biggest reason is that the VGA module within the BIOS is different. Even if it is for the same video chip, how that chip gets set up to drive a CRT or LCD display is different. The various LCD displays are far from standardized so it is very likely the VGA module of the IO BIOS has setup routines unique to the IO and its LCD video display. I took my test one step further and extracted the VGA module from a 10/99 IO BIOS and replaced the VGA module of the Advantech BIOS with it. I flashed this to the IO and tried to boot. Unfortunately it still did not work. I figured it would be a long shot, and it was. --duvell 04-28-2000 15:40:11
