If for some odd reason, you think it's RAM module/size related, I
suggest you go over your BIOS settings with a fine

BIOS", and "Hole at 1MB boundary" (or 15-16MB boundary). Perhaps try;
if there's a "Load Setup Optimized Defaults" (BUT... note ALL your
orig. settings Prior).
I'll do that. There isn't a lot in the BIOS though, it's extremely
basic. I borrowed my old 512mb dimm back today and tried it on its own
- didn't resolve the issue.

May even look into Flashing that BIOS,
I'll try that next - maybe something got messed up somehow.


some munged ROM or CMOS/NV-RAM code....HP may also be using an area of
the HDD to *store* your NV-RAM data, and the ROM BIOS is just a
'pointer' to that *hidden* HDD area.

try;
# hdparm -I /dev/hda

By chance - is that a Matsushita DVD-RAM drive ? (or similar?)
Yes it is. What's the significance?

Output of hdparm -I /dev/hda - I'm not sure what to look for:
