90 CBLID Cable ID Select – Used to detect the presence of an 80 conductor IDE cable
on the primary IDE channel. This allows BIOS or system software to
determine if it is necessary to enable the high-speed transfer modes (DMA66
or DMA100).
91 RXD- Half of Ethernet Analog Twisted Pair Receive Differential Pair – This pin and
pin-93 make up the Receive twisted pair and receive the serial bit stream on
the Unshielded Twisted Pair Cable (UTP).
92 PIDE_D8 Primary Disk Data 8 – Refer to J4, pin-58 for more information.
93 RXD+ Part of Ethernet Analog Twisted Pair Receive Differential Pair – Refer to pin-
91 for more information.
94 NC Not Connected
95 TXD- Half of Ethernet Analog Twisted Pair Transmit Differential Pair – This pin
and pin-97 make up the Transmit twisted pair and transmit the serial bit
stream on the Unshielded Twisted Pair Cable (UTP).
96 PIDE_D7 Primary Disk Data 7 – Refer to J4, pin-58 for more information.
97 TXD+ Part of Ethernet Analog Twisted Pair Transmit Differential Pair – Refer to
pin-95 for more information.
98 HDRST* Hard Reset – Low active hardware reset (RSTDRV inverted)
