When you attempt to use the Drive Converter (FAT32) conversion utility, you may receive the following error message:
Does not support interrupt 13 extensions
This issue can occur if your Small Computer System Interface (SCSI) hard disk is partitioned with the FAT16 file system and the interrupt 13 extensions (INT13) option on your SCSI adapter is disabled or is not fully supported.
: Changing settings on your SCSI adapter my result in data loss. Because of this, use caution before performing the following procedure.
To resolve this issue, enable the interrupt 13 extensions (INT13) option on your SCSI adapter. For information about how to do so, contact your hardware vendor, or view the documentation included with your SCSI adapter.
Windows 98 uses logical block addressing (LBA) on most SCSI drives to
access data. With drives using the FAT32 file system with interrupt 13
extensions, Windows depends on the Basic Input/Output System (BIOS) to fully support the interrupt 13 extensions.
