3.4.3.1 Primary Master / Slave Sub-Menu
The system displays advanced details like the number of heads/cylinders/sectors on
the detected disk and the maximum storage capacity of the disk.
This option lets you set the following hard disk parameters:
Type
Selects the type of device connected to the system.
Options: None / ATAPI Removable / CD-ROM / IDE Removable / Other ATAPI /
User / Auto
Multi-Sector Transfers
This option allows you to specify the number of sectors per block for multiple sector
transfers.
Options: Disabled / 2 Sectors / 4 Sectors / 8 Sectors / 16 Sectors
LBA Mode Control
Enables or disables LBA Mode.
In LBA Mode, instead of referring to a cylinder, head and sector number, each
sector is instead assigned a unique "sector number". In essence, the sectors are
numbered 0, 1, 2, etc. up to (N-1), where N is the number of sectors on the disk.
In order for LBA to work, it must be supported by the BIOS and operating system,
but since it is also a new way of talking to the hard disk, the disk must support it as
well. All newer hard disks do in fact support LBA, and when auto detected by a
BIOS supporting LBA, will be set up to use that mode.
