I got the same problem.... I'm using a Powermac 8600 and it says the same when i try to install....
'No CDROM device found'
i press ok, it says:
'Please insert the Additional Drivers floppy'
well.... i searched.... no drivers.img (or what ever called driver) on the cd-rom...
try'd other floppy's even Debian & YDL CDROM driver floppy's none of them works, it just says:
'Floppy is not a Linux ext2 floppy' (well it is !!!! 100% sure)
i don't get it.....
please help !!!!!
thanx in advance
