Can you do that to the s2885 for me? I am busy working on the
VGABIOS support and have to brain for that.

Please refer s4882 to change the MB that you support.
nodeid = lapicid() & 0xf;
orm with initial apic id
nodeid = (cpuid_ebx(1) >> 24) & 0xf;

YhLU,
You change the cpu_init_detected(void) to cpu_init_detected(nodeid),
what should I put in the nodeid? You break EVERY K8 mainboard we
have.
Ollie
Stefan,
Please check out the code from the CVS code.
After LinuxBIOS keeps the bsp to still use apicid 0. Kernel (2.6.10) x86-64
can work well.
Andi suggest that. But I wonder why the normal BIOS (kernel with acpi
enabled) can lift that to 0x10. --- normal BIOS (kernel with acpi disabled)
will fail too.
I also CC the kernel guys relating to this.

Enable apic ext id committed.
Changes
Auto.c
nodeid = lapicid() & 0xf;
#if ENABLE_APIC_EXT_ID == 1
enable_apic_ext_id(nodeid);
lapic_write(LAPIC_ID, ( lapic_read(LAPIC_ID) |
(APIC_ID_OFFSET<<24) ) ); // CPU apicid is from 0x10
#endif
if (cpu_init_detected(nodeid)) {
asm volatile ("jmp __cpu_reset");
}
distinguish_cpu_resets(nodeid);
also reset_test.c
change cpu_init_detected and distinguish_cpu_resets to take node id.

How to use linuxbios together with openbios? Is there
any clear howto doc? What's the main purpose of
openbios? What's the main difference between openbios
and filo?
Now I'm using filo to boot my linux kernel.
tks

Hi!
I have the
motherboard 9IGLM with
Intel 845GL chipset.
I know that this motherboard is not supported by LinuxBIOS (am I right?)
but I ask you: what would be happen, if I would update the flash EPROM with
LinuxBIOS?
I run on my PC the MS Win2000 and Debian GNU/Linux Woody.
And I have one more question:
memtest86 v3.1 says:
Unexpected Interrupt - Halting
Errors: 261 905
Type: Gen_Prot
I configured the memtest:
Cache Mode: Always On
Test Selection: All Tests
Address Range: Test All Memory
Memory Sizing: BIOS - All
If in the configuration the Memory Sizing: BIOS - is not All,
then the memtest not reports errors.
Is my BIOS then defective or not?

Thanks, and sorry for my English

Is there a flash rom utility I can use to flash linuxbios to my EEPROM?
Currently I am WICE to do it. But I can't depend on a hardware device to
update bios.

Yes.

Surely you should at least enable ApicExtBrd too. Otherwise
0xf will send to all CPUs.

Hello,
It turns out that the VGABIOS support can be made pretty generic
for all kinds of PCI expansion ROM. So I have the emulator the
.init method of default_pci_ops_dev. I am going to add the following
directories, if there is no objection, I will commit it next week.
src/include/x86emu -- public header file of x86emu
src/devices/pci_rom.c -- expansion ROM loading and execution
src/devices/emulator -- the emulator and supporting functions
src/devices/emulator/x86emu -- the emulator itself
src/devices/emulator/pcbios -- legacy PC BIOS handler for the emulator
src/devices/emulator/biosemu.c -- glue between pci_rom.c and the
emulator
Any comments ?
Ollie
Apologies if this is a redundant contribution.
None of my pc motherboards have JTAG or HW debug capabilites.
And constantly (hot)flashing, changing ram init code, then (hot)flashing again
gets old really fast.
Looking around, I couldnt find any debug tools that would operate at
basically the reset vector level. I thought this was the goal of openbios,
but I got lost in all the jibberish about 4th and firmware standards.
So I set out to make a small interactive low level shell with the goal
of providing at least some tools to aid in board/memory bringup and debugging.
This was nontrivial given the system limitations, however I got a few
things to work.
Attached is llshell.inc (for linuxbios1, Ive not tried any of the new
stuff yet) and llshell_linux (for running/testing inside of linux).
It's written entirely in asm and can run in a memoryless early stage
(say at the beginning of ram_set_registers or points afterword).
List of commands:
beep -- pc speaker beep
rst (or RST) -- reset
out(b,w,l) <val> <port> -- raw out val at port
in(b,w,l) <port> -- show raw port value
jmp <address> -- jmp to address (llshell addr is in eax)
call <address> -- funcion call (assumes a working stack)
cli -- clear interrupts
sti -- enable interrupts
push <value> -- push value onto stack
pop -- pop from stack and display
wm(b,w,l) <addr> <val> -- write mem
dm <addr> <lines> -- dump mem
mcp <src> <dst> <size> -- mem copy
mpat <pat> <dst> <size> -- mem pattern
memt <begin> <end> -- memory test
pcir(b,w,l) <loc> -- pci read config
pciw(b,w,l) <loc> <val> -- pci write config
dl <addr> <size> -- memory download (display xor cheksum at completion)
cram <addr> <size> -- enable cache to be ram (experimental)
baud <val> -- change baudrate (not yet implemented)
exit -- exit shell
All values in hex (0x prefixing ok)
