1. Features of mahogany.
The code can run on the Mahogany board, which is one of sample boards
made by AMD. Its major features are:
CPU (only K8 system):
* AMD AM2+
* AMD Athlon 64 x2
* AMD Athlon 64 FX
* AMD Athlon 64
* AMD Sempron CPUs
System Chipset:
* RS780E
* SB700
On Board Chipset:
* BIOS - SPI
* Azalia CODEC - Realtek ALC888
* LPC SuperIO - ITE8718F(GX).
* LAN - REALTEK 8111C
* TPM - SLB9635TT1.2
Main Memory:
* DDR II * 4 (Max 4GB)
Expansion Slots:
* PCI Express X16 slot*2 (PCI-E X8 Bus)
* PCI Express X4 Slot*1
Intersil PWM:
* Controller - Intersil 6323
2. The ACPI feature is already added. I suggest that firstly we can test
the board without the ACPI by setting the HAVE_ACPI_TABLE as 0.
With Rev F processor, the HT link can only work in HT1, whose max
frequency is 1GHz.
