Hello all,
I have an early IBM PC (5150) w/ 64K on the motherboard.
This machine has the early BIOS bug that prevents it from
recognizing over 544KB of RAM.
Is there a device driver that can be used to fix up the
memory area where the BIOS stores the amount of RAM? The
area needs to be fixed up before DOS loads, or DOS won't see
the changes.
Also, is there a restriction on using an EGA card in this
machine? I have a monochrome display adapter card in it;
attempts to use EGA (either standalone or with the MDA) have
failed. I think I'm setting the motherboard switches
correctly. The EGA card in question is a genuine IBM card;
two different samples have not worked.
Thanks,
Mike
