Hi
I have troubles with a Amiga 1000 Golem ram expansion.
Each time I reach 800 Kb of 2 Mb available I have a guru.
I tried to change memory chips but no change.
So, I need to tell my workbench 1.3 not to use bad memory.
I have tried with nofastmem + addmem (start memory) (end memory) but it doesn't work (memory already mounted).
I tried to disable memory with the switch and addmem : no ram expansion found.
Another idea ?
A utility called memeat, available on aminet can cordon off blocks of RAM, but I do not believe you can specify an address range.
I'm not sure if any addmem command can specify a bank of RAM on an expansion board to be allocated.
I do agree with the posters above that grounding issues in the A1000 are about as likely as a bad RAM chip (maybe 50/50 chance.) Are you sure it's the RAM board? Have you been able to try other expansions on this 1000, or this 1000 using other expansions?
