POST Code
0x6A Display external cache size on the screen if it is non-
zero.
0x6C Display shadow message
0xCA post EISA init
0x70 Check flags in CMOS and in the TrustedCore data
area for errors detected during POST. Display error
messages on the screen.
0x72 Check status bits to see if configuration problems
were detected. If so, display error messages on the
screen.
0x4F Initialize MultiBoot. Allocate memory for old and new
MultiBoot history tables.
0xCD Reclaim console vector after HW vectors initialized.
0x7D Initialize Intelligent System Monitoring.
0x7E The Coprocessor initialization test. Use the floating
point instructions to determine if a coprocessor
exists instead of the ET bit in CR0.
0xC1 Check Boot Type (Server BIOS)
0x80 Disable onboard COM and LPT ports before testing
for presence of external I/O devices.
0xCA Redirect Int 15h to enable target board to use remote
keyboard (PICO BIOS).
0x88 Initialize interrupt controller.
0x81 Run late device initialization routines.
0x87 Initialize motherboard configurable devices.
0x85 Display any ESCD read errors and configure all PnP
ISA devices.
0x82 Test and identify RS232 ports.
0x84 Test and identify parallel ports.
0x86 Initialize onboard I/O and BDA according to CMOS
and presence of external devices.
0x83 Configure Fisk Disk Controller.
0xCE Initialize digitizer device and display installed
message if successful.
0x89 Enable non-maskable interrupts.
0x8C Initialize both of the floppy disks and display an error
message if failure was detected. Check both drives
to establish the appropriate diskette types in the
TrustedCore data area
0xCB Redirect Int 13h to Memory Technologies Devices
such as ROM, RAM, PCMCIA, and serial disk (PICO
BIOS).
0xCD Remap I/O and memory address space for PCMCIA
(PICO BIOS).
0x90 Initialize hard-disk controller. If the CMOS ram is
valid and intact, and fixed disks are defined, call the
fixed disk init routine to initialize the fixed disk
system and take over the appropriate interrupt
vectors.
