Hi Mike,
>command+option+shit+delete
You take it to the crapper with you? heheh...
Anyway - this is a bug with Supermacs and unsupported cd drives made
worse by ageing laser lenses, wierd keyboards etc. If you can boot from
the zip with 7.6 you can either replace the apple cd driver on it with a
third party driver like the charismac cd extension or replace it with the
hacked version of the apple driver which will work with just about all cd
drives. I'll mail you both if you want them
If your boot cd is a copy containing the apple driver and the cd is
not supported by that driver you cannot boot from it - are the 508's
Toshiba?
The Umax disk should work as it has the FWB CDrom Toolkit driver -
but you should perhaps check to see if it's on there...
I've booted from Traxdata, Toshiba, Matshita and Plextor with the
hacked apple driver. Or you can try the latest apple cd/dvd driver which
does work on some cd roms not previously supported.
If your laser lens is iffy it may have trouble reading the cd's -
but you can take it apart and clean the lens carefully with a damp cotton
bud - no chemicals.
