Thx! Will try to clean contacts and test it with VMT. All contacts are visually in good condition and no bad soldering on board, but i check it once more. I didn't mean contacts of the pin header connector but contacts between memory chip pins and PCB. It may not be visible there's a cracked solder …

Hi, I don't have experiance with Matrox Mystique cards but I think the memory module should be similar to Millennium module. So there is not any extra pin that would identify presence or memory size of the module. The memory size is probed automatically at boot by videobios. Did you try to run VMT - …

I also made a SMD xtal adapter for old boards with DIP sockets, but it was just a side project to fill free space on 10 x 10cm panel :) I also finished and tested my 4MB WRAM memory expansion module for Matrox Milllennium II (fixed ver 1.1), mentioned in this thread: https://www.vogons.org/viewtopic …

If you have a digital scope or logic analyser it may be usefull to view and compare some FDD signals timing of working and not-working boot sequence. Just a guess, if FDC/ISA clock is independent on CPU clock there may still be a timing difference if BIOS would use e.g. some delay loop that Harris …

Could't be possible that changing CPU with different speed may affect floppy signals timing? Does it boot with different CPU but the same speed?

Hi, did you managed to boot it up? I just got the same board from a friend. It's populated with ceramic Pentium MMX and 2 SIMMs, no DiskOnChip. Unfortunatelly the ZIF CPU socket has missing the lever so the CPU pins are not secured to have good contact. I have no idea who did what with it. I have to …

Sure that MGA 8MB is CAPABLE 1600x1200/24bpp because I tried it under Windows 3.1 and DOS (as I wrote in 1st post). So this is not RAMDAC limitation but pure software limitation. Even MGA has one of fastest WRAM and 250MHz RAMDAC. I found a spec of MGA G200 and it should support up to 1920x1200/16M …

Ok, that makes sense as they provide also driver for NT-Alpha64 that is quite rare - I don't have any other VGA with Alpha drivers. But Creative Labs and Diamond was aimed more to gamers so they could spent some money to implement VBE on theirs cards. They rather belived that windows gaming is the …

I'm a bit confused about this. I belived that 8MB is far enough because 1 frame takes 7,6MB in 32bpp or 5,7MB in 24bpp that fits in 8MB. But it seems that Windows require some extra reserved VRAM for some internal buffers - do we know how much exactly? I can only say it's less than 2 full frames. I …

Yes, some programs displays mess with UniVBE... I still wonder how it is possible on a card from 1997 where VESA was widely accepted standard and every other card had much better VBE implementation.

Thanks for confirmation. So it seems all this Permedia 2 cards use poor 3Dlabs videobios with just customized boot-up message so only workaround is to load UniVBE/SDD...

Hi, I saved this PCI VGA from a scrap because seemed to me interesting when I recall old reviews from '90 it was some kind of Pro card for 3D/CAD apps and quite high priced so I never touched this till now.

In meantime I was lucky to buy an 8MB version of MGA II PCI from a scrap man just for 2e so primary reason for making memory expansion board disappeared but when it's almost done I'll keep going to finish it anyway. I also bought another 4MB AGP MGA II so I have 8 spare WRAM chips now...

Just a random seek for Alpha took me to this interesting thread :) Did you managed to make your VGA working? When it works fine in other x86 MB I doubt the VGA is damaged but maybe something wrong on Alpha MB around PCI bus... BTW I'm quite disappointed by Q2 performance - the native Alpha build. I …

BTW I have recently found a cool russian forum https://smd.db-x7.ru/load/skhemy_materinskikh_plat/283 that contains a lot of schematics of motherboards, even quite modern ones like my Gigabyte GA-P67-DS3-B3 and GA-P67A-D3-B3. This helps a lot for HW modding and repair.

I think it really doesn't worth for the power consumption, noise and other complications esp. for a gamer's computer. I always preferred high (over)clocked C2D/i7 over many core xeons with usually lower clock. CwF - yes, 1st gen. core MBs still had floppy (also some Gigabytes), nice to have...
