Main menu - Making system settings
Type - Hard Disk Type
This field is used to specify the type of hard disk drive.
If the hard disk supports this mode, the setup menu reads the hard disk parameters
Auto
from the disk itself. You do not need to select the parameters yourself.
You can enter the hard disk parameters yourself.
User
If you have set the hard disk parameters with Autotype Fixed Disk, you can only reduce
the values.
You cannot change the hard disk parameters (Cylinders, Heads, Sector/Track and Write
None
Precomp.). An IDE drive has not been installed.
If, for example, a CD-ROM drive is inserted into the notebook, or a CD-ROM drive is
CD
built into the MobiDock, this item enables you to boot the system from the CD-ROM
drive.
Cylinders, Heads, Sectors/Track, Write Precomp - hard disk parameter
These hard disk parameters are set in accordance with the IDE hard disk drive. If you want to change
the hard disk parameters manually, set the Type field to User.
Multi-Sector Transfers - Block Transfer
This field specifies the transfer mode for the IDE hard disk drive.
One block is transferred for each interrupt.
Disabled
2 Sectors, 4 Sectors, 6 Sectors, 8 Sectors, 16 Sectors
The set number of blocks (sectors) is transferred for each interrupt. This enhances
performance.
LBA Mode Control - Addressing
This field enables and disables the LBA (Logical Block Addressing) mode. If a hard disk supports LBA
mode, the LBA mode allows you to set up and use hard disks with a capacity of more than 528 Mbytes.
The default entry depends on the installed IDE hard disk drive. Change the default entries only if you
are installing another hard disk drive.
You may only use IDE drives in the LBA mode selected when they were set up. In other
!
words, if you set up a hard disk with LBA mode disabled, you may only operate the hard disk
with LBA mode disabled.
The BIOS uses the hard disk parameters and supports a maximum capacity of 528
Disabled
Mbytes.
If the hard disk supports LBA and it has a capacity of more than 528 Mbytes, the BIOS
Enabled
translates the hard disk parameters, allowing the disk's full capacity to be used. This
allows the disk's full capacity to be used.
