This read-only bit is a 1 to indicate that the Intel
Reserved. Hardwired to 000b.
SOP_MODE_CAP — RO. This read-only bit is a 1 to indicate that the secondary
controller supports both legacy and native modes.
SOP_MODE_SEL — R/W. This read/write bit determines the mode that the secondary
IDE channel is operating in.
0 = Legacy-PCI mode (default)
1 = Native-PCI mode
POP_MODE_CAP — RO. This read-only bit is a 1 to indicate that the primary controller
supports both legacy and native modes.
POP_MODE_SEL — R/W. This read/write bits determines the mode that the primary
IDE channel is operating in.
0 = Legacy-PCI mode (default)
1 = Native-PCI mode
Sub Class Code (SCC) — RO.
01h = IDE device, in the context of a mass storage device.
Base Class Code (BCC) — RO.
01 = Mass storage device
Cache Line Size (CLS) — RO.
00h = Hardwired. The IDE controller is implemented internally so this register has no
meaning.
