3.2.1 IDE  Primary/Master, Primary/Slave Setup 

Computer detects IDE drive type from drive C to drive F. 

Press Enter on any of the Primary/Master, Primary/Slave options to view advanced details of 

the corresponding drive. The system displays advanced details like the number of 

heads/cylinders/sectors on the detected disk and the maximum storage capacity of the disk. 

Multi Sector Transfers 

This option allows you to specify the number of sectors per block for multiple sector transfers. 

16 Sectors / 2 Sectors / 4 Sectors / 8 Sectors /Disabled 

LBA Mode Control 

Enables or disables LBA Mode.  

When LBA is turned on, the BIOS will enable geometry translation. This translation may be 

done in the same way that it is done in Extended CHS or large mode, or it may be done using 

a different algorithm called LBA assist translation. The translated geometry is still what is 

presented to the operating system for use in Int 13h calls. The difference between LBA and 

ECHS is that when using ECHS the BIOS translates the parameters used by these calls from 

the translated geometry to the drive s logical geometry. With LBA, it translates from the 

translated geometry directly into a logical block (sector) number. 

Disabled / Enabled 

32 Bit I/O 

Enables or disables 32 bit data transfer mode. 

Enabling this option causes the PCI hard disk interface controller to bundle together two 16 bit 

chunks of data from the drive into a 32 bit group, which is then transmitted to the processor or 

memory. This results in a small performance increase. 

Enabled / Disabled
