Fast Primary Drive 1 Base Clock (FAST_PCB1) — R/W. This bit is used in
conjunction with the PCT1 bits (D31:F2:4Ah, bits 5:4) to enable/disable Ultra ATA/100
timings for the Primary Slave drive.
0 = Disable Ultra ATA/100 timing for the Primary Slave drive.
1 = Enable Ultra ATA/100 timing for the Primary Slave drive (overrides bit 1 in this
Fast Primary Drive 0 Base Clock (FAST_PCB0) — R/W. This bit is used in
conjunction with the PCT0 bits (D31:F2:4Ah, bits 1:0) to enable/disable Ultra ATA/100
timings for the Primary Master drive.
0 = Disable Ultra ATA/100 timing for the Primary Master drive.
1 = Enable Ultra ATA/100 timing for the Primary Master drive (overrides bit 0 in this

Scratchpad (SP1). ICH8 does not perform any action on these bits.
Secondary Drive 1 Base Clock (SCB1) — R/W.
0 = 33 MHz base clock for Ultra ATA timings.
1 = 66 MHz base clock for Ultra ATA timings
Secondary Drive 0 Base Clock (SCBO) — R/W.
0 = 33 MHz base clock for Ultra ATA timings.
1 = 66 MHz base clock for Ultra ATA timings
