Interpretation/Description
During L2 cache initialization, the processor is running at a faster or
slower bus frequency than it is designed for. This is a fatal error, and
the processor will be halted. Detected during cache initialization.
No memory was detected during the memory initialization. This is a
fatal error, and the processor will be halted.
Unsupported memory was detected during the memory initialization.
This is a fatal error, and the processor will be halted.
An invalid timing configuration was detected (e.g. 66 MHz SDRAM
with a 100 MHz host bus frequency).
Both registered and unregistered DIMMs were detected.
An unsupported memory configuration was detected.
The stack was located above 1 Mbyte when attempting to switch to
real mode by a call to the sflDone16 API.
The detected amount of memory does not match the SPD data.
Unsupported The host bus frequency is not supported.
The requested integrity mode is not supported by the Hardware.
Board initialization(SIO, GPIO(A/V Mute) etc.)
Prepare to handle interrupts
initialize caching and shadow ROM to RAM
Super I/O initialization
Initialize local keyboard if present
initialize ATA
chipset pci resource allocation
board specific resource allocation hook
enable memory and i/o address decoding for pci devices
Standard legacy services setup
initialize memory map
Setup the graphics mode for 830M
