The Switching Power Supply must meet ATX 2.03 specification with ATX12V1 Power
connector. Your ATX power supply 5V standby power must be able to provide at least a
720mA current capacity.

PCI slot 3 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 3, you may
encounter some problems. Furthermore, if your Operating System doesn't allow peripheral
devices to share IRQ signals with each other, such as Windows
install a PCI card into PCI slot 3.
#
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 CD-ROM to HPT 372 IDE connector (IDE3 & IDE4).
#
This motherboard supports the standard bus speeds of 66 MHz/100 MHz/133 MHz that are
used by specific PCI, processor and chipset specifications. Exceeding these standard bus speeds
is not guaranteed due to the specific component specifications.
