In order to avoid this problem and prevent the risk of data corruption, the Delayed Write
function of the ICP cache must be disabled during the complete installation. To do so,
use the ICPCON program, choose Advanced Setup, Configure Controller, Controller Settings and
switch the Delayed Write function OFF. After having completed the Windows NT installation,
switch the Delayed Write function ON again.
Step 3 – Check the Master Boot Record.
In some cases Windows NT checks the virtual geometric parameters (heads, sectors) of the
ICP Controller BIOS Host Drives during the installation process. This can cause Windows
NT to calculate wrong parameters. In this case, the first part of the installation procedure
(text mode) seems to work fine, but after the first warm boot the installation terminates
irregularly because the Windows NT boot loader is no longer available. To avoid this prob-
lem, we recommend that you re-create the so-called master boot record (MBR) of the given
Host Drive. Therefore load in ICPCON the Configure Host Drives menu and then Overwr. Master
Boot Code. You should never use Overwr. Master Boot Code when the Host Drives already
contain valid data.
