48-bit LBA Test Program for Windows* Me/98 SE/98

The MS-DOS*-based 48-bit LBA test program below can be used on systems running Windows* Millennium Edition (Me), Windows* 98 SE, or Windows* 98 to determine if the BIOS is capable of supporting hard drives larger than 137GB (48-bit LBA). The program will provide one of the following results:

  • PASSED - BIOS is currently 48-bit LBA capable. No additional steps required.
  • FAILED - BIOS is currently not 48-bit LBA capable. BIOS update needed.
  • UNDETERMINED - Test program is not able to determine if BIOS is 48-bit LBA capable.
The 48-bit LBA test program was designed to run in a true MS-DOS environment - not an MS-DOS prompt window. (Instructions for running the program in true MS-DOS can be found at the bottom of this page). Running this test program from an MS-DOS prompt from within Windows Me, Windows 98 SE or Windows 98 may work but you may see some irregularities and formatting issues.

Note: Due to the current BIOS architecture, you will need to have a hard drive larger than 137GB installed on your system before running this test program. Otherwise, the following error message will appear: "We cannot determine whether your BIOS is 48-bit LBA capable, because you currently do not have a 48-bit LBA hard drive installed."

Caution: Running this test program on systems using non-supported operating systems such as Windows XP, Windows 2000, and Windows NT* 4.0 will produce a 'NTVDM.EXE' error.

Please note that no personal information of any type is sent or obtained by running this 48-bit LBA test program.
If you choose to run this program, the test program performs a check of your system to determine if your BIOS is currently 48-bit LBA capable or if it may need to be updated. No information of any type is collected or returned back from your system to Intel.
