6.9 Operation of LS120 Drives
Note: In the IPC5600/IPC5600C, BIOS enables the LS120 drives (which are actually IDE
devices e.g. CD-ROM drives) to operate like a floppy disk drive (drive letter A or B). However, it
is only possible to use standard diskettes (360 KB, 720 KB, 1.44 MB) with the LS120 drive. The
option to work with special 120 MB diskettes is not a built-in feature of BIOS and must be
supported by the operating system.
If a LS120 drive is operated without a second floppy disk drive (in BIOS "Floppy A = None" and
"Floppy B = None"), see section "Standard CMOS Setup", then it can be accessed as the A drive
and therefore can also be booted.
If another additional floppy disk drive is being used (parallel to the LS120 drive) to the external
floppy disk drive interface, then the floppy disk drive is operated as drive A and the LS120 drive
is operated as drive B. In this case, the expression "LS/Zip" (found in BIOS under the menu item
"BIOS Features Setup") must be first in the "Boot Sequence" parameter so that the LS120 drive
can be used for booting .
