Master Drive / Slave Drive PIO Mode
These fields allow your system hard disk controller to work faster. Rather
than have the BIOS issue a series of commands that transfer to or from
the disk drive, PIO (Programmed Input/Output) allows the BIOS to
communicate with the controller and CPU directly.
The system supports five modes, numbered from 0 (default) to 4, which
primarily differ in timing. When Auto is selected, the BIOS will select the
best available mode.
IDE Primary/Secondary Master/Slave UDMA
These fields allow your system to improve disk I/O throughput to
33Mb/sec with the Ultra DMA/33 feature. The options are Auto and
Disabled.
IDE HDD Block Mode
This field allows your hard disk controller to use the fast block mode to
transfer data to and from your hard disk drive.
Onboard LAN Boot ROM
This feature allows users to enable or disable the onboard LAN boot
ROM. The default setting is Disabled
