Perhaps you experienced this before, but what I'm noticing is that because my UMC chipset has the infamous "E" on it for EDO support, regardless of which RAM type is installed, when set to "EDO" in the BIOS the L2 cache works. Even with FPM installed, and the BIOS set to "Normal", L2 doesn't work.
I'm guessing this is another unforgettable PC Chips moment?... 🤣
I have not run into this exact problem with the E chipsetted PC Chips boards. As was the case with PC Chips, board issues were never predictable from one board to the other.
Sorry to ressurect a dead thread.
I keep ending up here after building a 486 dx4 - 100 with a M919 board.
For those who come after me;
If you get a Cache stick (I got a new one of the remakes from the us.) You will need to set the ram type to EDO and the timings to 3.1.3 for it to work stable.
For reference my board is a DX-9700 1.0 or the pc-chips M919 ver 3.3b/f. Mine has the fake "write-Back" Plastic squares on the board.
My example also had a faulty serial 1.
I got caught by a European seller who thought this was a top of the line 486 board and sold it with 16 meg of edo and an amd 5x86-p75 ADW version.
I have a 486DX4-100 and 64 Megabytes of ram, A soundblaster 16, a Diamond viper PCI and a 4gb hdd. all i need to find now is the vesa extensions that are not shareware.
I spent a fair while trying to figure out exactly what was going on, and i thought to let anyone else who had this issue after 2022 and kept landing on this thread what the fix was.
Good travels all who come after me.
