When the host writes to the IDE Sector Number In Register (IDESNIR), this register is
updated with that value.
17.3.2.10 IDESNIR—IDE Sector Number In Register (IDER—D22:F2)
Address Offset: 03h Attribute: R/W
Default Value: 00h Size: 8 bits
This register implements the Sector Number register of the command block of the IDE
function. This register can be written only by the Host. When host writes to this
register, all 3 registers (IDESNIR, IDESNOR0, IDESNOR1) are updated with the written
value.
Host read to this register address reads the IDE Sector Number Out Register
IDESNOR0 if DEV=0 or IDESNOR1 if DEV=1.
17.3.2.11 IDECLIR—IDE Cylinder Low In Register (IDER—D22:F2)
Address Offset: 04h Attribute: R/W
Default Value: 00h Size: 8 bits
This register implements the Cylinder Low register of the command block of the IDE
function. This register can be written only by the Host. When host writes to this
register, all 3 registers (IDECLIR, IDECLOR0, IDECLOR1) are updated with the written
value.
Host read to this register address reads the IDE Cylinder Low Out Register IDECLOR0 if
DEV=0 or IDECLOR1 if DEV=1.
17.3.2.12 IDCLOR1—IDE Cylinder Low Out Register Device 1 Register (IDER—
D22:F2)
Address Offset: 04h Attribute: R/W
Default Value: 00h Size: 8 bits
This register is read by the Host if DEV = 1. Intel Server Platform Services Firmware
writes to this register at the end of a command of the selected device. When the host
writes to the IDE Cylinder Low In Register (IDECLIR), this register is updated with that
value.
