For some time I've been trying to setup a "4386-VC-V" motherboard ( https://stason.org/TULARC/pc/motherboards/U/U … -4386-VC-V.html ) with 128 MB of RAM so that I could use it with Linux.
The board is currently populated with 256 KB of external cache and a 486 DX33 MHz CPU.
According to the stason link this CPU should allow 128 MB of RAM.
But unfortunately when I run memtest-86 v3.0 any attempts to use over 32 MB of RAM results in all kinds of errors.
If I use 32 MB or less memtest-86 V3.0 completes with no errors.
I've tried both 30-pin PARITY and 30-pin NON-PARITY memory modules -- in each case 8 modules of 16 MB each.
The board appears to be somehow currently (?) limited to addressing 32 MB of RAM
On bootup I see this:
AMIBIOS (C)1992 AMerican Megatrends Inc.,
The BIOS chip label on the motherboard says "1993".
Could there be some BIOS update I need to do in order to allow use of 128 MB of RAM?
Would anyone be able to provide the instructions on how to proceed with a BIOS update?
Thanks for any help in advance...
