I/O Interface Controller - SOYO SY-P4IS2 User Manual

Motherboard Description
diskett's 2,490 tracks per inch (tpi) containing up to 120MB of data
storage. A conventional diskette uses 135 tpi for 1.44MB of data storage.
LS-120 drivers are ATAPI-compatible and connect to the motherboard's
IDE interface. (LS-120 drivers are also available with SCSI and parallel
port interfaces.) Some versions of Windows 95 and Windows NT
operating systems recognize the LS-120 drive as a bootable device in both
120MB and 1.44MB mode.
Connection of an LS-120 drive and a standard 3.5-inch diskette drive is
allowed. The LS-120 drive can be configured as a boot device if selected
as Drive A in the BIOS setup program.
¿
Note
If you connect a LS-120 drive to an IDE connector and configure it as
the :boot: drive and configure a standard 3.5-inch diskette drive as a "B"
drive, the standard diskette drive is not seen by the operating system.
When the LS-120 drive is configured as the "boot: device, the system will
recognize it as both the A and B drive.
