i have the Asus VL/I-486SV2GX4 rev 2.1 and the Asus VL/I-486SV2GX4 rev 2.0 - the first one is my primary mainboard in my dx4 config. somewhere this is an "issue", because these boards from 1995/96 and i targeted an early dx4 config from 1994. i got a Asus VL/I-486SVGOX4 rev 1.2, maybe this the earliest asus mainboard for dx4 - it is prepared for the 3.3v cpus, but the bios (Award 1994.04.26) supports just the code names (p24c), and no lba support. i put the gx4 rev 2.0 bios (Award 1995.01.11) to this board, it looks fine. i would be happier, if i could use a late 94 bios with real dx4/lba support.
has somebody an earlier bios for this series? i have:
Asus VL/I-486SVGOX4 rev 1.2 Award 1994.04.26 (actually with Award 1995.01.11)
Asus VL/I-486SV2GX4 rev 2.0 Award 1995.01.11
Asus VL/I-486SV2GX4 rev 2.1 Award 1995.08.22
i have rebuilt the fan, the cpu is a intel wb cache dx4 (maybe i will replace with a more authentic wt version).

very typical cheap dx4 vlb board from 95/96 - opti895a, the bios id says "lucky star" (typical east european brand in the middle of 90s). i cannot identify exactly the model, but similar to 486 VL3 CACHE (MV035E). surprisingly the opti895a outperformed in more benchmark tests the sis471 - it looks the vlb timing is more aggressive. the default bios settings are very slow.
