I've been trying to install FC4 on a known good iMac (iMac 500MHz/20GB 384MB CD-ROM) for about 3 days now.
Having read every installation document I could find I'ver tried all sorts of things to get it installed.
Although I initially tried a dual-boot setup (with Mac OS X Tiger) I gave up due the number of problems I was encountering e.g repeated error messages "The partitionís data region doesnít occupy the entire partition" & "Attempt to read sectors 16-18 outside of partition on /dev/hda"
Since then I've being doing a CD ISO install and choosing the Desktop Installation option with automatic partitioning.
The installation appears to go smootly.
On reboot I see the following:
"Invalid ROM signature 8181 should be 0xaa55"
failed to create dev/consol, dev/null & dev/zero.
Completed first boot and reached login screen. A single beep is heard at this time.
Entered user name and password then took minutes to eventually arrived at the desktop.
Now the mouse appears to freeze for long periods (about a minute at a time) and doing anything is thus painfully slow.
I've run top from a shell and found no unusual CPU hogs. X is using about 2.3% cpu and nothing else it using any more.
Back in GUI selecting 'System Tools' from the 'Applications' menu has me waiting for about a minute again. There's also no hard disc activity while this is happening. It just pauses.
Any suggestions would be appreciated. Help getting dual-boot working at some stage would be great too. Happy to take small steps first...
