Hello,

i am looking for a BIOS dump for my Chaintech board. The original BIOS is damaged. Found a BIOS for Version M1.04 but it does not support all features (like Game port) and has some reliability issues with 2nd level cache.

Would be glad if someone could provide the correct BIOS to me.

Thanks a lot in advance an best regards!

Closest I could find on Chaintech's old website: https://web.archive.org/web/19980212085635/ht … tw/BIOS/486.htm
You might also want to try and search for "4SPM" instead of "486SPM" - based on what I can see on Total Hardware 99, they appear to have a very similar layout.

Thanks a lot!!!

There are two versions in your link, the 306 (for rev. 5/6) and 124 (for rev. 3/4). My board seems to be rev. 2. At least the 306 was this one that i tested with cache issues and no game port support.
The 124 is new for me, i have hope that it could help! 😀 I reply in three weak becaus of vacancy, thanks!

best regards
