Have a 300mhz Beige G3 running 9.2.2 and 10.4.8
Sometimes the G3 can access the CD drive and other times it can't.
When it can't, a PRAM reset via the keyboard will always get it
recognized and going again... but it may become unrecognized again
after a few minutes.
I've replaced the original Apple drive with a newer Apple CD-RW drive
from a G4 Digital Audio with no change. I've also installed a fresh
PRAM battery with no change. Any ideas?
There's some goofball firmware restriction that bootable drives on the
Beige must be set to master. You can boot a slave CD only using
XPostFacto's helper disk boot process whereby the boot starts off on
a master device, and is then transferred to the slave device. If you
have only one bootable CD and one bootable HD they need to be on
separate busses and both set to master. The Rev.A ROMs don't even
support slave devices at all, so they both must be master for Rev.A
ROMs. For Rev.B C you'll need to be sure the CD drive is set to
master if you want to boot it directly using the C key or with
startup disk. I normally left my CD drive set to slave and used XPF to
enable slave drive booting on those rare occasions I needed to boot a
CD. Alternatively, XPF's Helper Disk boot can also enable booting from
Firewire devices, so a FW CD is also a bootable option.
