Hi!

FF heisst, dass das BIOS die Kontrolle an das OS abgegeben hat. Also nachdem alle Checks (POST, Erweiterungskarten usw.) durch sind und keine Fehler aufgetreten sind.

Um aus dem Handbuch meines Epox zu zitieren:
C-1 POST CODES
POST (hex) DESCRIPTION
CFh Test CMOS R/W functionality.
C0h Early chipset initialization:
- Disable shadow RAM
- Disable L2 cache (socket 7 or below)
- Program basic chipset registers
C1h Detect memory
- Auto-detection of DRAM size, type and ECC.
- Auto-detection of L2 cache (socket 7 or below)
C3h Expand compressed BIOS code to DRAM
C5h Call chipset hook to copy BIOS back to E000 & F000 shadow
RAM.
0h1 Expand the Xgroup codes locating in physical address 1000:0
02h Reserved
03h Initial Superio_Early_Init switch.
04h Reserved
05h 1. Blank out screen
2. Clear CMOS error flag
06h Reserved
07h 1. Clear 8042 interface

0Ah 1. Disable PS/2 mouse interface (optional).
2. Auto detect ports for keyboard & mouse followed by a
port & interface swap (optional).
3. Reset keyboard for Winbond 977 series Super I/O chips.
0B-0Dh Reserved
0Eh Test F000h segment shadow to see whether it is R/W-able or
not. If test fails, keep beeping the speaker.
0Fh Reserved
10h Auto detect flash type to load appropriate flash R/W codes
into the run time area in F000 for ESCD & DMI support.
11h Reserved
12h Use walking 1’s algorithm to check out interface in CMOS
circuitry. Also set real-time clock power status, and then
check for override.

values are MODBINable by OEM customers.
15h Reserved
16h Initial Early_Init_Onboard_Generator switch.
17h Reserved
18h Detect CPU information including brand, SMI type (Cyrix or
Intel) and CPU level (586 or 686).
19-1Ah Reserved
1Bh Initial interrupts vector table. If no special specified, all H/W
interrupts are directed to SPURIOUS_INT_HDLR & S/W
interrupts to SPURIOUS_soft_HDLR.
1Ch Reserved
1Dh Initial EARLY_PM_INIT switch.
1Eh Reserved
1Fh Load keyboard matrix (notebook platform)
20h Reserved
21h HPM initialization (notebook platform)
22h Reserved
