Imac, OS8.5, Ramdrive problem

Hello

imac keeps crashing (bomb message, no error number) just after 'starting up' screen.
Booted from cd's, ran first aid. Internal Ram drive has errors that first aid can not repair.
Is this a virtual drive? or is it the RAM itself?

How do I correct the errors (delete or reset the Ramdrive)? or is it a hardware problem (replace RAM)?

Thanks.

Maybe the memory is the problem.  What model iMac, and can you get to  the memory modules.  I had an early iMac (sage, DVD) where the memory (installed by MacMall) went south.  It took a long time to narrow it down to the memory, but once I replaced that the machine has been spotless.  If you've got two or memory modules, remove them and boot with one module at a time.  It should be apparent if memory is the problem, and which module is the cause.

It's an early tray loade.
I don't understand if the 'ramdrive; is referring to a virtual drive or if it's the actual RAM chips.
I've popped the chips out and put them back to no avail.
Strangely I can't get DiskWarrior to boot on it either.
Think I'll just scrap it.

Did you reset the PROM with the CUDA switch?

Not knowing what model iMac you have, I would say that you should do a google search on this to find out where the switch is loacated.  Just another suggestion...

RAM disk is a memory option at startup.  In other words, it is virtual and you can either have it on or off when the machine boots.

If your machine normally boots under OS 9 and you can still boot from the CD, then boot from the CD.  If your machine boots under OS X let me know.

See if you can go to the "Memory Control Panel" and click the RAM disk button off, and then see if you can have a successful reboot.  If the RAM disk shows as "off" already, then you might want to consider reinstalling the OS.

Here's a link for more discussion of RAM disk plus a screen-shot of the Memory Control Panel:
