7-4 Operating System-Related Errors

Different drive lettering under Windows NT
This may happen when using a SCSI card in addition to the RAID Function . Windows
NT does not necessarily load the driver for the boot device controller first. This results
in a drive that in MS-DOS is the C: drive being the D:, or E:, etc. in Windows NT. Use
Windows NT's Disk Administrator utility to reassign the letters which NT has assigned
to the drives. See your Windows NT documentation for instructions on how to use
Disk Administrator.
The Operating System no longer boots after creating a Mirrored Array using
your existing boot drive using Windows 98/NT4/2000
This is due to Drive Geometry issues. You can verify this if you move the original drive
back to the onboard controller and it boots. Each controller can view a drive differently.
This can be an issue for a new controller which loads the original Master Boot Record
(MBR) and then has a problem translating it or the Operating System boot record.
For Windows NT or Windows 2000, Promise recommends a "clean" install of the
Operating System. This restores the MBR and OS boot record. You will then need to
repartition and format the drive.
For Windows 98,you can perform the DOS Command "SYS C: "from a bootable
floppy or CD-ROM to restore the operating system boot record and transfer the
system files to the boot drive. If this does not work, the Windows 98 registry may have
become corrupted during the boot process and must be restored. See the Windows
documentation to perform this procedure.

Windows may already be listing the controller under "Other Devices" instead of "Hard
disk controllers" section. In Device Manager under "Other Devices" to see if it lists a
"PCI Card", or "RAID Controller". If so, highlight this listing and click on the "Proper-
ties" button, and then click on the "Driver" tab. Depending on your version of
Windows, choose either "Change Driver" or "Update Driver". Then follow the on-
screen prompts to complete installation of the driver. If Windows asks if you want to
test if the device can be removed safely click on "CANCEL. Reboot the system to
complete installation of the driver.
