Software • BIOS for System Unit with Socket 370
IDE HDD Block Mode
Switches the block mode on/off for the hard disk. If the block mode is Enabled,
then more sectors are simultaneously transferred at data transfer resulting from
the increase in speed.
On-Chip Primary/Secondary PCI IDE
The integrated IDE interface is equipped with two IDE channels, which can be
switched on and off separately here.
IDE Primary/Secondary Master/Slave PIO
The PIO (Programmed I/O) fields let you select a PIO mode (0 to 4), and the
AUTO mode for all connected IDE devices (theoretically four: two channels per
interface). The PIO mode specifies the maximum transfer speed on the IDE bus.
Modes 0 through 4 provide successively increased performance. The AUTO
setting automatically selects the best mode for each device.
With older hard drives and ATA Flash disks, setting the PIO mode too
high can cause read and write errors. Therefore we recommend that
you select the AUTO setting.
IDE Primary/Secondary Master/Slave UDMA
If a connected IDE device supports an Ultra DMA mode, then this is detected by
the AUTO setting and the respective mode is set.
USB Keyboard Support
Enables the use of a USB keypad to the USB port.
If you want to avail of a USB keypad and you are using an operating
system other than Windows 98/2000, then Power Management must be
switched on for the USB keypad to function properly (see section
"Power Management setup").
Init Display First
Determine the display device that will be initialized first.
Onboard FDC Controller
Switch the integrated floppy disk controller on or off. If it is disabled, the floppy disk
drive does not function any longer.
