Internal PCI/IDE
The SiS 5598 chipset contains a PCI IDE interface that supports 2 IDE channels:
Primary (IRQ14) and Secondary (IRQ15). Each channel supports 2 IDE devices, so the
system is capable of supporting a total of 4 IDE devices. Select Primary, Secondary, or
Both to activate chipset IDE interface(s) installed on your system board.
IDE Primary/Secondary Master/Slave PIO
The 4 IDE PIO (Programmed Input/Output) fields allow you to set a PIO mode (0-4)
for each of the 4 IDE devices that the onboard IDE interface supports. Modes 0 through
4 provide successively increased performance. In “
Auto”
mode, the system
automatically determines the best mode for each device.
IDE Primary/Secondary Master/Slave UDMA
Ustra DMA/33 implementation is possible only if your IDE hard drive supports it and
the operating environment includes a DMA driver (Windows 95 OSR2 or a third-party
IDE bus master driver). If your hard drive and your system software both support Ultra
DMA/33, select “
Auto”
to enable BIOS support.
IDE Burst Mode
Selecting “
Enabled
” reduces latency between each drive read/write cycle, but may
cause instability in IDE subsystems that cannot support such fast performance. If you
are experiencing disk drive errors, try setting this value to “
Disabled
”. This field does
not appear when the Internal PCI/IDE field, above, is “
Disabled
”.
