Important additional information
Assignment of Drive Letters
The MS-DOS operating system assign drive letters to primary
partitions first. After the primary partitions have been assigned
drive letters the logical partitions are assigned drive letters. Do not
assume that the drive letter designations will follow consecutively
from device to device within a PC system.
An Example:
A PC system is configured with an IDE hard disk as the boot
drive, a SCSI hard disk, and a CD-ROM drive. The IDE drive has
three partitions: one primary and two logical. The SCSI hard disk
has two partitions: one primary and one logical. The SCSI hard
disk is assigned ID 1, and the CD-ROM is ID 4. The distribution
of the drive letters will be:
A: 3½" floppy drive
B: 5¼" floppy drive
C: IDE primary partition
D: SCSI primary partition
E: IDE first logical partition
F: IDE second logical partition
G: SCSI logical partition
H: CD-ROM
WINDOWS 3.0 & 3.1
NCR DOS SCSI drivers are compatible with Windows 3.0 and 3.1.
No additional drivers or configuring is needed.
