Large Disk Access Mode
This option determines whether a hard drive with more than 1024 cylinders,
more than 16 heads and or more than 64 tracks per sector is present on the
system. Set this option to
DOS if such a hard drive is present. Else, set this
option to Other . Virtually, all modern hard disks have these characters so leave
this option at DOS , unless you know otherwise.
DOS / Other
Legacy USB Support
When enabled, the BIOS takes control of the USB ports. Enable this only if you
run an OS that does not support USB (e.g. DOS) or when you have USB
hardware like USB mice that you want to use even before the operating system
loads.
Enabled / Disabled
