Using floppy disk drives and floppy disks
Keep the following in mind when you use floppy disks:
m In the PC environment, the floppy disk drives are A and B.
m In the PC environment, you cannot use a Mac OS–format floppy disk. If
you insert one, it will be ejected.
m To eject a floppy disk in the PC environment, press x-E.
m To use an unlocked PC floppy disk with the Mac OS, you must switch to
the Mac OS environment before inserting the disk. You can use a locked
PC disk freely in both environments.
m In the PC environment, blank disks are formatted for the PC. In the Mac
OS, you can format disks for either environment.
m Some blank disks are preformatted. If you insert a new, blank disk in the
PC environment and it is ejected, it may have been preformatted in Mac OS
format. To use the disk in the PC environment, you can switch to the Mac
OS and format the disk for the PC. For instructions, see the documentation
that came with your computer or Mac OS software upgrade kit.
Restarting the PC from a floppy disk
To restart (reboot) the PC using a floppy disk, insert a floppy disk containing
operating system software into the disk drive. Press Control-Alt-… to restart
the PC.
Using CD-ROM discs and drives
Keep the following in mind when using CD audio discs and CD-ROM discs
and drives:
m In the PC environment, press x-Y to eject a disc. If the disc cannot be
ejected (because a file is in use or the disc is being shared), you will hear
a beep.
m You can start an audio CD in either environment and continue to listen
when you switch environments. (If you start up and switch to the PC while
listening to an audio CD, there may be a delay of several seconds while the
PC starts up.)
