Note
!
PCI slot 1 shares IRQ signals with the AGP slot.
!
PCI-4 and USB controllers share an IRQ.
!
If you want to install two PCI cards into those PCI slots that share IRQ with one another at the
same time, you must make sure that your OS and PCI devices’ driver supports the IRQ sharing
function.
!
PCI slot 5 shares IRQ signals with the HPT 372 IDE controller (supports Ultra DMA 133). The
driver for HPT 372 IDE controller supports IRQ sharing with other PCI devices. But if you install
a PCI card that doesn’t allow IRQ sharing with other devices into PCI slot 5, you may encounter
problems. Furthermore, if your Operating System doesn’t allow peripheral devices to share IRQ
signals with each other, such as Windows
®
NT for example, you can’t install a PCI card into PCI
slot 5. (KR7A-133R Only)
!
HPT 372 IDE controller is designed to support high-speed and high performance mass storage
devices. Thus, we suggest that you don’t connect non-disk devices that use ATA/ATAPI
interfaces, such as a CD-ROM, to HPT 372 IDE connector (IDE3 & IDE4).

3-8. PC Health Status
You can set the warning and shutdown temperatures for your computer system, and you can check the fan
speeds and power supply voltages of your computer system. The features are useful for monitoring all the
important parameters within your computer system. We call it the
PC Health Status .
