Get IDE IO port registers' base addresses by mode. In 'Compatibility' mode,
use fixed addresses. In Native-PCI mode, get base addresses from BARs in
the PCI IDE controller's Configuration Space.
The steps to get IDE IO port registers' base addresses for each channel
as follows:
1. Examine the Programming Interface byte of the Class Code fields in PCI IDE
controller's Configuration Space to determine the operating mode.
2. a) In 'Compatibility' mode, use fixed addresses shown in the Table 1 below.
<pre>
___________________________________________
| | Command Block | Control Block |
| Channel | Registers | Registers |
|___________|_______________|_______________|
| Primary | 1F0h - 1F7h | 3F6h - 3F7h |
|___________|_______________|_______________|
| Secondary | 170h - 177h | 376h - 377h |
|___________|_______________|_______________|
Table 1. Compatibility resource mappings
</pre>
b) In Native-PCI mode, IDE registers are mapped into IO space using the BARs
in IDE controller's PCI Configuration Space, shown in the Table 2 below.
<pre>
___________________________________________________
| | Command Block | Control Block |
| Channel | Registers | Registers |
|___________|___________________|___________________|
| Primary | BAR at offset 0x10| BAR at offset 0x14|
|___________|___________________|___________________|
| Secondary | BAR at offset 0x18| BAR at offset 0x1C|
|___________|___________________|___________________|
Table 2. BARs for Register Mapping
</pre>
@note Refer to Intel ICH4 datasheet, Control Block Offset: 03F4h for
primary, 0374h for secondary. So 2 bytes extra offset should be
added to the base addresses read from BARs.
For more details, please refer to PCI IDE Controller Specification and Intel
ICH4 Datasheet.
