When you run Windows 98 Setup on a Toshiba Tecra computer, you may receive
the following error message:
Setup could not create files on your startup drive and cannot set up
Windows. If you have HPFS or Windows NT file system, you must create
an MS-DOS boot partition. If you have LANtastic server or SuperStor
compression, disable it before running Setup.
Some Toshiba Tecra computers were shipped with incorrect information in
the hard disk partition table. As a result, Setup detects a problem with
the hard disk. In this case, the partition table indicates that extended
INT13 calls are not available. Regular INT13 calls work only in real (or
Run Windows 98 Setup from MS-DOS.
Toshiba Tecra computers are shipped with the hard disk partitioned into
two logical drives: a 2-gigabyte (GB) drive C using the FAT16 file system,
and a 2.75-GB drive D using the FAT32 file system.
Windows 98 Setup verifies the integrity of the file system on the drive on
which it is being installed by using BIOS INT13 calls to read raw sectors
from the disk. The partition table on some Tecra computers prevents these
calls from working.
Depending on the information in the partition table and/or the values
returned from the BIOS, Setup use either regular INT13 calls or extended
INT13 calls. In this case, the partition table indicates that extended
INT13 calls are not available [SUWIN:IsExtendedInt13() always returns
FALSE] because the system indicator in the partition table for drive C is
0x06, which indicates a non-FAT32 file system drive. However, the regular
INT13 calls work only in real mode. In protected mode, the call returns
invalid data, such as a few random characters at the front of the buffer
and then words running sequentially from 0x05 to 0xFF and starting over
