Operating System-Related Errors
Different drive lettering under Windows NT
This may happen when using a SCSI card in addition to the Promise chip. 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.
Promise Windows driver does not appear Device Manager
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 “Properties” 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.
