Hi, all.

Recently I've found an LPX Socket 3 machine. The motherboard is FIC 486-JAL. Here are its jumper settings on stason.org and here is the manual.

Problem is, the system doesn't detect any L2 cache — at least, none of it shows up in POST screen.

The L2 cache is divided into two banks. There are no jumpers to set the cache configuration (unless I'm missing something).

Bank 0 is socketed (and was empty when I got the board), Bank 1 is soldered on. So when I looked on Stason, I've noticed that all the cache configurations need Bank 0 to be filled. So my current configuration is the following:

Bank 0: 4 DIP-20 chips. Each chip has the following markings: HY534256S-70 9205A
Bank 1: 4 DIP-20 chips. Each chip has the following markings: HY534256AS-70 9416A

It seems like I've even got nearly matching chips. Yet the system still doesn't detect any cache.

Otherwise the configuration is the following:

Intel Overdrive DX4-100
32MB FPM RAM
Cirrus Logic CL-GD5428
Onboard Promise IDE controller
3COM 3C515 NIC
Sound Blaster Pro 2 CT1600

What am I missing?
