Re: EB164 SRM Problems - Followup
Doh... I could of course consider to chage my ways, but then I'ld have to
run the thing _without_ VGA card... Since SRM doens't seem to support my (or
any?) ISA cards... And when I'ld remove the 4Port NIC I'ld have to replace
it with 2 other single port NIC's, and thus still have no space for a PCI
graphics card... But then, if the ECC correction doens't work under ARC, I
suppose it'd be the better choice?
