I installed a 575 motherboard in my CC yesterday.

(These are the specs: 32 MB RAM, 1 MB VRAM, Asante ethernet card - untested, 2GB Seagate HD, external 600e CD drive.)

I haven't done the soldering video mod, so I changed the boot ID in Resedit. This seemed to work fine (though I didn't really know what I was doing). It booted first time - seemed OK.

But I've got two problems:

1. The system is eating up almost all the available memory - leaving about 1MB spare for apps. That shouldn't be happening, should it?

2. I want to install Mac OS 8 (the hard drive had 7.5.5 on it). But the CC is very fussy about which floppy it will boot with. I typically get this error message: "Sorry, a system error occurred. bus error. To temporarily turn off extensions, restart and hold down the shift key." (Turning off extensions makes no difference.)

I finally got it to boot from the Disk Tools floppy that comes with the Mac OS 8 installation disk. I wiped the hard drive. But two partitions on it - one with 7.5 and the other with 8 - but it won't boot from either. Same error message.

I didn't really know what I was doing in Resedit - the whole thing is a bit of a blur. Do I need to go through that again? If it worked once, doesn't the CC know think it's an LC 575? It continues to boot from Disk Tools fine.

Oh, and I also get occasional dead/sad Macs against a black screen...

Any suggestions gratefully received. Thanks.

Go to the "Memory" control panel and enable "32 bit addressing". If the system is set to "24 Bit Addressing" all memory above the 8MB mark is essentially disabled. (It will show as "System", but it's not doing anything with it.)
