IDE HDD Block Mode
Enables hard disk drive block transfer mode . The setting op-
tions are:
Enabled (default)
Disabled
IDE Primary/Secondary Master/Slave PIO
These four lines set the hard disk PIO transfer mode, which
affects the hard disk data transfer rate. The system will auto-
detect the PIO mode of a device in any of these positions when
they are set to 'Auto', the recommended setting. Alternatively,
you can set the mode manually. Modes 0 to 4 are supported.
IDE Primary/Secondary Master/Slave UDMA
These four lines set the hard disk UltraDMA transfer mode,
which requires a drive that supports this data transfer method.
The system will auto-detect an UltraDMA device in any of the
four EIDE channels when these are set to 'Auto', the default set-
ting. The other setting is Disabled. You can leave this set to Auto
without effect if there are no UltraDMA devices installed.
On-Chip Primary/Secondary PCI IDE
Enables or Disables the Primary or Secondary PCI controllers.
Selecting "Disabled" releases IRQ14 ( for Primary) or IRQ15 (for
Secondary).
Enabled (default)
Disabled
USB Keyboard Support
Enables or Disables support for a USB keyboard. Enable this if
you connect a USB keyboard. The default is Disabled.
