each of the four IDE devices that the onboard IDE interface supports. Modes 1 through
4 provide successively increased performance. In Auto mode, the system automatically
determines the best mode for each device. The choices are: Mode 0, Mode 1, Mode 2,
Mode 3 and Mode 4.
IDE Primary Master/Slave UDMA:
Ultra DMA implementation is possible only if your IDE hard drive supports it and the
operating environment includes a DMA drive (Windows 95 OSR2 or a third-party IDE
bus master drive). If your hard drive and your system software both support Ultra DMA,
select Auto to enable BIOS support. The choices are Auto and Disabled.
ISA Decode Memory:
Enable to select memory range to decode ISA ROM
IT8888 ISA Decode IO:
Select IT8888 ISA IO Resource
IT8888 ISA Decode Memory:
Select IT8888 ISA memory Resource
IDE HDD Block Mode:
Block mode is also called block transfer, multiple commands, or multiple sector
read/write. If your IDE hard drive supports block mode (most new drives do), select
Enabled for automatic detection of the optional number of block read/write per sector the
drive can support. The available choices are Enabled, Disabled.
Onboard Serial Port 1/2/3/4:
This feature allows you to manually select the I/O address and IRQ for the first and
second serial ports. If is recommended that you leave it as Auto so that the BIOS can
select the best settings for it. But if you need a particular I/O port or IRQ that’s been
taken up by this serial port, you can manually select an alternative I/O port or IRQ for it.
You can also disable this serial port if you do not need to use it. Doing so frees up the
I/O port and IRQ used by this serial port. Those resources can then be reallocated for
other devices to use.
UART Mode Select:
Select an operating mode for the serial port, the choices are: Normal, IrDA, ASKIR,
SCR.
UR2 Duplex Mode:
In an Infrared port mode, this field appears. Full-duplex mode permits simultaneous
two-direction transmission. Half-duplex mode permits transmission in one direction only
at a time. Select the value required by the IR device connected to the IR port.
Onboard Parallel Port:
This feature allows you to select the I/O address and IRQ for the onboard parallel port.
The default I/O address of 378H and IRQ7 should work well in most cases. Unless you
have a problem with the parallel port, you should leave it at the default settings. The
