Attribute:
See below.
EIDE Controller Primary Command Base Address
DevB:1x10
Default:
0000 01F1h.
Attribute:
See below.

PROGIF[2]. Secondary native mode.
Read-write. 0=Compatibility mode for secondary port;
DevB:1x18 and DevB:1x1C are ignored and not visible; address decode is based on legacy
addresses 170h-177h, 376h; DevB:1x3C[7:0] Read-only zeros; DevB:1x3C[15:8] = 00h; IRQ15 may
be used by the IDE controller. 1=Native mode; DevB:1x18 and DevB:1x1C are visible and used for
address decode; DevB:1x3C[7:0] read-write; DevB:1x3C[15:8] = 01h; IRQ15 mapped to PIRQA per
Section 3.4.2.1 on page 41 and used exclusively by the secondary IDE port.
PROGIF[1]. Primary native/compatibility mode selectable.
Read-only. This is High to indicate that
PROGIF[0] is read-write.
PROGIF[0]. Primary native mode.
Read-write. 0=Compatibility mode for primary port; DevB:1x10
and DevB:1x14 are ignored and not visible; address decode is based on legacy addresses 1F0h-
1F7h, 3F6h; DevB:1x3C[7:0] Read-only zeros; DevB:1x3C[15:8] = 00h; IRQ14 may be used by the
IDE controller. 1=Native mode; DevB:1x10 and DevB:1x14 are visible and used for address decode;
DevB:1x3C[7:0] read-write; DevB:1x3C[15:8] = 01h; IRQ14 mapped to PIRQA per Section 3.4.2.1 on
page 41 and used exclusively by the primary IDE port.
REVISIONID.
Read-only. EIDE Controller silicon revision. The value of this register is revision-
dependent.

31:3
Description
BASE[31:3] Port Address.
Read-write. These bits specify an 8-byte I/O address space that maps to
the ATA-compliant command register set for the primary port (legacy I/O space 1F0h-1F7h).
Note: when DevB:1x08[8] is Low, the primary port is in compatibility mode and this register is ignored
and not visible (reads as 0000_0000h).
Read-only. 001b.
