Maybe you can try to resolder the pins of all the chips, I use the same memory chip, but the PCB version is Rev.24, it does not have the EDO/FPM switch, it works fine on both the 486DLC and 386SLC motherboards, in the BIOS Memory parity is turned off.

If the chip is very old and you want to protect that fragile sticker, or you have encountered a fake ROM chip, you can try this method to determine the model of the ROM chip. 1. Select a ROM model in Xgpro at will, for example, select AT27C256, and then start reading the ROM chip, then the software …

If you have an ISA network card installed, you can install the XTIDE Universal BIOS ROM chip on it, or make a standalone ISA 8bit mini card for it, except for the disadvantage that it will occupy an ISA slot, it is perfect.

Nooo, that's a 486 SLC, a 16-bit version of the IBM Blue Lightning CPU. I've got a mainboard with the 32-bit version 486DLC from some ambra LPX computer and it's got the same heatsink. You can tell it's 16-bit because of the PLCC co-processor socket. Another clue in the BIOS string: "30-0100-006305 …
