GigaBit Ethernet to the Desktop - Client2 Configuration
|
The chipset on this motherboard (Intel 845G) is unable to perform disk I/O at speeds over 3 MB/S. This is a common problem with chipset IDE channels. If you're not sure about the disk I/O speed of the motherboard chipset that you intend to use with GigaBit, it is strongly suggested that a PCI disk controller be used.
