SVBus

NT 5.* - TXTSETUP.OEM

Installing Windows NT 5.* (Windows 2000 / XP / 2003) to a virtual disk requires the installation of the SVBus driver at an early stage of the process using the Press F6 if you need to install a third party SCSI or RAID driver... option - a floppy disk image can be used.

If the system firmware is configured to boot in AHCI mode then Windows NT 5.* systems will likely fail to find any attached storage as the NT 5.* Operating Systems shipped without integrated AHCI drivers. AHCI drivers are also installed using the Press F6 if you need to install a third party SCSI or RAID driver... option. ReadMe.txt included in the SVBus download states "...if you need another AHCI driver for your chipset you may have to create a custom TXTSETUP.OEM file on the floppy disk image...", however no further instructions are provided. The following demonstates how to create a custom TXTSETUP.OEM file for SVBus and iaStor.sys driver.

The following pages contain useful reference information -

Step 1

The contents of TXTSETUP.OEM for the SATA AHCI Controller on the test system -

Step 2

Having traced the required menu option to iaAHCI_7_1 (using Hardware Device IDs), the other entries can be removed. Edited TXTSETUP.OEM file with a single entry for iaAHCI_7_1 -

Step 5

Combine the entries from Step 2 and Step 4 into a single TXTSETUP.OEM file. Note that one of the [Disks] entries has been removed and the tagfile element in the remaining [Disks] section is set to the name of a file on the modified disk (see here for more information) -
