Legacy USB Option
MS-DOS and Windows NT operating systems do not recognize USB. A
new BIOS option, Legacy USB, is available in BIOS Version 2.2.1.1 for
NCR 7452 and 7453 terminals. The default setting is Disabled. Enabling
the Legacy USB option in the 7452 terminal BIOS makes the 5932 USB
Keyboard look like a PS/2 keyboard to MS-DOS. For more information
about 7452 BIOS Setup options, refer to the NCR 7452 Hardware User's
Guide (BD20-1373-C).
Services Considerations
When performing any of the following DOS services, the Legacy USB
option must be enabled prior to using the service.
• DOS Loadable Diagnostics
• OS Recovery
