Configuring Windows NT 4.0 to use the Adaptec
1510 SCSI card on the FT1200
Problems have been encountered with installing an Adaptec 1510 card into
the FT1200 running Windows NT 4.0. As default the Windows NT driver for the Adaptec 1510
uses IRQ11, this is also used by the onboard 7880 controller on the FT1200. If this is
left unchanged, NT will fail to boot and display an "INACCESSABLE BOOT DEVICE"
error.
The Windows NT Adaptec 1510 driver can be re-configured to use a
separate IRQ address. This can be done by editing the Windows NT System Registry.
Install the Adaptec 1510 card into the FT1200, making sure that the
jumper on the card is set to IRQ 9 (the 1510A card is controlled by jumpers on the card,
the 1510B card is controlled by software and can be configured using the 1510CFG
program available from Area 41 of the BBS).
Select Settings, Control Panel, SCSI
Adapters. Click on the Drivers tab option and select Add, choose Adaptec from the
Manufacturers list and Adaptec AHA-1510 SCSI Host Adapter from the SCSI
Adapter list box and click OK.
You will be asked "Do you want to restart your computer now
?", select No and click OK. (If you continue to reboot the system you will not be
able to boot NT because of the "INACCESSABLE BOOT DEVICE" error).
The System Registry should then be modified to change the IRQ address of
the 1510 card.
The following steps should be taken to modify the System Registry:-
Select Start, Run and enter REGEDT32
as the program name to invoke the System Registry Editor
Select the HKEY_LOCAL_MACHINE on Local Machine section
Select SYSTEM
CurrentControlSet
Services
Sparrow
Once Sparrow is selected add the following by using Edit,
Add Key :-
Parameters
Device0
Select Device0, choose Edit and Add
Value
Enter Value: DriverParameter, accept data type REG_SZ
Enter string IRQ=9
Once the above has been completed exit the System Registry and shutdown
Windows NT. Windows NT is now configured to use the Adaptec 1510 card and will not try to
boot from this device.
