The CMOS Memory size in AT&T machines and HP Vectra's and similar animals is
less than 640K (in the AT&T case, this is caused by counting base memory
starting with "0" instead of "1", so it ends up with 639K). The original
unmodified 0.1 code was very, very sensitive to base memory not being
*exactly* 640 in CMOS.
Use a patched kernel (I think my fix for this is still patch 3) and the
problem will "go away", or use one of the fixes in the original FAQ..
