16.5 BIOS Setup
IDE Channel 0 Master, IDE Channel 0 Slave
The system jumps to the following submenu when you select this type of menu field:
Figure 16-5
Type
Multi-Sector
Transfer
166
IDE Channel 0 Master (example)
[User]
Select "User" to enter a user-specific definition of the hard disk
type. Configure all the other options, for example, Cylinder, Heads,
Sectors/Track, or other properties of the hard disk drive.
[Auto]
The parameters which you can select in this dialog are usually
saved to the respective IDE drive. The "Auto" setting in the "Type"
field means that these values are automatically read from the drive
and written to memory.
If Type is selected for a drive that does not exist, a timeout is
triggered within approximately 1 minute and the entries remain
unchanged. It makes sense only to set "Auto" for interfaces to
which a drive is connected.
[CD/DVD-ROM]
CD/DVD-ROM is connected
ATAPI
A removable data volume is connected
Removable
None
Select "None" if you have not connected a disk drive. This setting
reduces system waiting time.
The number of blocks (sectors) transferred per interrupt are defined at the "Multi-
Sector Transfer" option. The value depends on the drive and should only be set by
way of "Auto" setting at the "Type" field.
