Correcting BIOS Limitations and Partitioning Using
Disk Manager
Your BIOS might contain limitations that can cause operational
failures when you install one of the new and larger hard disk drives.
See the documentation that comes with your IBM computer to install
your hard disk drive, and to configure your system.
The following procedures contain steps to solve most known BIOS
limitations using manual overrides and the Disk Manager software.
Attention: The following steps do not apply to IBM computers.
1. Access your configuration-setup information.
2. Select the drive number for the new drive that you are installing.
Based on BIOS type, number of IDE controllers, and number
of IDE devices in your computer, the configuration-setup
program displays options for up to four devices.
Normally drives 1 and 2 are connected to the primary IDE
controller and drives 3 and 4 are connected to the secondary
IDE controller.
If you have two IDE controllers, drives 1 and 3 are the
master devices and drives 2 and 4 are the slave devices.
If you have one IDE controller, drive 1 is the master device
and drive 2 is the slave device.
3. Based on your configuration, at least one of the following options
(listed in order of preference) is available. Do one of the
following:
a. Select the Auto Detect configuration-setup option if it is
available.
If the correct disk capacity is shown, exit, save the
configuration setup, and go to “Using Your Operating
System For Partitioning.”
If the correct disk capacity is not shown, continue with
“Partitioning and Formatting Using Disk Manager.”
b. Select the User Definable drive type. The User Definable
entry for BIOS configuration will be a number between 47
and 49. Enter 1024 for cylinders, 16 for heads, and 63 for
sectors. Set the Landing Zone and Write Precomp entries to
zero. When the partitioning process completes, the drive
capacity is shown as 504 MB, but you can use the full
capacity of your drive. Save the changes, close the
configuration-setup program, and continue with “Partitioning
and Formatting Using Disk Manager.”
c. Select Drive Type 1. The value displayed for the type 1
drive is
1 MB
. When the partitioning process completes, the
drive capacity is shown as 10 MB, but you can use the full
capacity of your drive. Save the changes, close the
configuration-setup program, and continue with “Partitioning
and Formatting Using Disk Manager.”
