Hi all,
I've got my Macintosh Performa 6400/180 up-and-running after quite a bit of work (power supply rebuild, replacing dead IDE HDD with a CF card and adapter, replacing the non-working CD-ROM drive), and I want to install Mac OS 8 from CD. I have an original UK install disc, and although I can boot the machine from it, unfortunately it won't let me install the OS as "there isn't enough RAM available" - only 8MB RAM is shown under system information, which I am guessing is the RAM soldered on the mainboard. Both DRAM module sockets are populated, so surely there should be plenty more RAM available than that. Is this an installer software limit, or could there be a hardware issue? Or, am I overlooking something simple?
I greatly appreciate any assistance!
Many thanks,
Adam
