IDE Features

This motherboard provides:

•

IDE on the PCI local bus,

•

support for IDE modes 1, 2, 3, and 4,

•

two IDE connectors (up to four IDE drives),

•

32-bit data transfer,

•

IDE prefetch read buffer,

•

Logical Block Address (LBA) support, and

•

fast ATA support.

IDE Drive Assignments

If four IDE drives are connected, WINBIOS assigns the physical drive numbers. DOS assigns logical drive
letters:

IDE Drive

Drive

Number

Drive Letter if One

Partition on Drive

Drive Letter if Two

Partitions on Drive

Primary Master

80h

C:\

G:\

Primary Slave

81h

D:\

H:\

Secondary Master

82h

E:\

I:\

Secondary Slave

83h

F:\

J:\

IDE Autodetect

All parameters for all IDE drives assigned to the secondary IDE connector are automatically detected by
WINBIOS.

Caution

If the parameters for an IDE drive cannot be automatically detected

by WINBIOS correctly or if you are using a CHS (Cylinder-Head-

Sector) translation mechanism that is different than the native mode

of the IDE drive, the drive should not be attached to the secondary

IDE controller.
