Please when replying use "Reply to all" or manually make sure that
[e-mail] is included in cc: or to: fields.

Could you please add what other post codes are you getting before the
last one?

POST code error "EE"

[Abhinav Hardikar]

Sorry abt that. Damn those codes are displayed so fast. I had to use a camera to capture them.

I get the following codes:

10,11,40,24,25,55,66,9b

24 is ./cpu/intel/model_6ex/cache_as_ram.inc:254:    
25 is ./cpu/intel/model_106cx/cache_as_ram.inc:244:

Thanx

could you add more post codes somewhere around this:
./boot/hardwaremain.c:105:	cbfs_load_payload(lb_mem, CONFIG_CBFS_PREFIX
"/payload");

POST code error "EE"

[Abhinav Hardikar]

Ok. I added the post code but it isn't displayed on the card. And I haven't added any payload as the chip is only 128K and needs 47KB more to accommodate SeaBIOS.

Is your serial cable really working?

I recommend you to remove unneeded microcode updates. Check what is your
cpu model/cpuid and remove unneded stuff like I did:
for example I have modified these files:
./cpu/intel/slot_1/Makefile.inc // leave only your models
./cpu/intel/model_65x/model_65x_init.c //comment microcode includes

this should fit everything to ~80 kB

[Abhinav Hardikar]

Ok....

I think the file ./boot/hardwaremain.c:105:  wasn't compiled earlier. 
I commented the post code in the file as you said and it showed 26 which is hardwaremain.c

Ok

I did as you said. my CPU id was 68x and that was not added in the Slot-1 Makefile. Your method of removing all other CPUs  created a lot of space. So I added SeaBIOS. Coreboot started working. It didn't give any error. But the keyboard is not working so are the serial ports. The Null modem cable is working. I checked it with HyperTerminal and minicom.

BTW its midnight here. I'll do the rest tomorrow. 
Thanx for your help :)

That's great to hear it! One more board will be supported :)

You could try extracting pirq table from vendor BIOS using this tool
from coreboot: util/getpir

What is the board that you based on your experiments? :)

No problem :)

You could look if the right superio is selected in the config.

POST code error "EE"

[Abhinav Hardikar]

And yes I forgot to add I used the following coreboot images of:

Abit Abit BE6-II V2.0 
ASUS P2B-F
 ASUS P2B-LS 
ASUS P3B-F 
AZZA PT-6IBD 
MSI MS-6119

All of them worked well but keyb didn't.

Also you could comment that line where you get post code in
./arch/x86/lib/c_start.S:85:
so you could see the last post code you want.
