Integrated
peripherals
(Cont.)
IDE prefetch mode: If you IDE interface supports IDE prefetching this will allow for
faster drive access. Enabled
is faster, only disable
if not supported.
Init display first: If you have only 1 graphics card in your system this can be
ignored. If you have multiple graphics cards in your system,
select either PCI
or AGP depending on which one you want to use. This is useful for those
of you who have motherboards with graphics cards soldered
into the motherboard.
USB controller:
If you use USB devices then you'll need to leave this enabled. Otherwise disable
it, you'll free up an IRQ in the process too.
IDE HDD Block Mode: This setting allows for multi-sector transfers, enabled
is faster.
IDE 32-bit transfer mode: Select enabled to use
32-bit I/O accesses with your hard drive. This is faster,
although it has been known to cause data corruption in Windows
NT.
Onboard FDD
controller: If you use FDD's
(Floppy Disk Drives)
then you'll need to have this enabled.
Onboard
serial port 1: Use this to set/disable/change the
address for Serial port 1. You can manually
select an address for it, e.g. 3E8/IRQ4, disable
it altogether or set it to Auto.
I'd recommend leaving it set to Auto.
Onboard
serial port 2: Use this to set/disable/change the
address for Serial port 2. You can manually
select an address for it, e.g. 3E8/IRQ4, disable
it altogether or set it to Auto.
I'd recommend leaving it set to Auto.
Onboard
parallel port: Sets the address for the parallel
port to use. Leave it at the default setting unless you need
to change it to fix a resource conflict.
Parallel
port mode: Use this to select the operation mode for the Parallel Port. You
may need to check your motherboard manual to find this out. ECP
mode being the best. Depending on your choice one of the
following submenus may become available.
·
ECP mode use DMA:
Use this to select the DMA channel for ECP or ECP+EPP to
use.
Parallel port EPP type: When using EPP
mode you can choose between EPP
1.7 or EPP 1.9
