Soldering over surface-mount PLB cache is pretty challenging soldering work. If you're confident of your ability, you can try, but I'd recommend ruling out other options first.

- not aware of any cache <> BIOS issues on the PA-2005, but checking if there's a BIOS update is always a good idea.
- bad cache chips usually show up as memory errors, not appearing at all would make me suspect the control/power circuitry around the cache, or some damaged traces. The power cable is a bit in the way in your photo, but above the "V" of "300V" on the cable looks like it could be some pretty severe damage to the board (that white blob). Also don't entirely trust CT38

the Cap on CT38 looks fine.

the new BIOS
619j900.zip
1.3/1.31 AWARD BIOS ver. 619J900 08/21/97
1. Fix system boot-up failure when using K6 CPU with 586_3028D.
2. Added new parting table for 6x86MX CPU.
3. Fixed system hang-up while starting Win95 with MACFEE Virus-scan application.
4. Use Flash534.zip for flashing!

the one that's in there now looks to be the BIOS ver. 616J900 04/11/97 so it's a few Revs older

Here is a pic with out the power cable in the way

update: got the new BIOS 6.19J900 installed same deal no L2 cashe

i all so made sure and there is 3.3v going to the chips

Hey i know it is a little old but still... does anybody know how or were to get the bios of this board?
My bios chis is showing a very old version and i want to install a bigger disk (now i can not go beyond 8Gb and i would love to have 20 or 32Gb in there.
I found a hacked bios that supports up to 128Gb but this one i could not installed mismatch of my machine....

Anyone know if there is a official bios somewere, al links to the fic ftp are broken...

i did see my motherboard listed on some webpage and i had the newest bios but you need to know what Ver of the board you have.. ill see what i can come up with..

Have you tried Uniflash to flash your BIOS in real DOS?
Also peel off the label on the BIOS EEPROM and check what type of EEPROM it is. The jumper next to it is to set the EEPROM type.
Refer to http://pcrebuilding.altervista.org/9/download … c_mb_pa2005.pdf page 16 (PDF page 22) for configuration details.

Good luck! 😀
