E1-E8 EC-EE OEM memory detection/configuration error. This range is reserved for chipset vendors &
system manufacturers. The error associated with this value may be different from one
platform to the next.
Checkpoint Description
E0 Initialize the floppy controller in the super I/O. Some interrupt vectors are initialized. DMA
controller is initialized. 8259 interrupt controller is initialized. L1 cache is enabled.
E9 Set up floppy controller and data. Attempt to read from floppy.
EA Enable ATAPI hardware. Attempt to read from ARMD and ATAPI CDROM.
EB Disable ATAPI hardware. Jump back to checkpoint E9.
EF Read error occurred on media. Jump back to checkpoint EB.
F0 Search for pre-defined recovery file name in root directory.
F1 Recovery file not found.
F2 Start reading FAT table and analyze FAT to find the clusters occupied by the recovery file.
F3 Start reading the recovery file cluster by cluster.
F5 Disable L1 cache.
FA Check the validity of the recovery file configuration to the current configuration of the flash
part.
FB Make flash write enabled through chipset and OEM specific method. Detect proper flash
part. Verify that the found flash part size equals the recovery file size.
F4 The recovery file size does not equal the found flash part size.
FC Erase the flash part
FD Program the flash part.
FF The flash has been updated successfully. Make flash write disabled. Disable ATAPI
hardware. Restore CPUID value back into register. Give control to F000 ROM at
F000:FFF0h.
Checkpoint Description
03 Disable NMI, Parity, video for EGA, and DMA controllers. Initialize BIOS, POST, Runtime
