Port 60/64 Emulation
This BIOS feature allows you to enable emulation of I/O
ports 64h and 60h so that there is full PS/2 legacy support
for USB keyboards and mice. It is also useful in providing
USB keyboard and mouse support in Windows NT which
does not natively support USB.

The menu sets delay time for USB operations.
Item
USB transfer set transfers to an endpoint to complete
time-out within a specific time.
• If set to zero, transfers will not time out
because the host controller will not cancel
the transfer. In this case, the transfer waits
indefinitely until it is manually canceled or
the transfer completes normally.
• If set to a nonzero value (time-out inter-
val), the host controller starts a timer when
it receives the transfer request. When the
timer exceeds the set time-out interval, the
request is canceled.
Device reset This option sets the reset timing for the
time-out USB Mass Storage to be initialized.
When set to 10 Sec, the BIOS will wait for
up to 30 seconds for the USB flash drive to
initialize.
Device This option sets the power-up timing for
power-up the USB Mass Storage to be initialized.
