Asus A7V8X needs a board enable.

[Luc Verhaegen]

Output from flashrom (from the .rar Glenn provided in a previous mail):

Calibrating delay loop... OK.
No coreboot table found.
Found chipset "VIA VT8235", enabling flash write... OK.
Found chip "SST SST49LF040B" (512 KB) at physical address 0xfff80000.
Flash image seems to be a legacy BIOS. Disabling checks.
ERASE FAILED!
Verifying flash... FAILED at 0x00000000!  Expected=0x95, Read=0x49

Output from lspci -vnnxxx attached.

Suggested ids:

Host Bridge KT400: 0x1106, 0x3189, 0x1043, 0x807F
  ISA Bridge VT8235: 0x1106, 0x3177, 0x1043, 0x808C

Board enable requires two things:

io(0x370) &= ~0x02;
    io(PM_IO_Base + 0x2C) |= 0x01;

The second scarily translates to: "Enable SMI generation".

The first is (according to carldani) most likely an io range for the 
super io. The superio is probably an it8712, but we do not know for 
sure, but there is a good chance that this is about dropping a gpio
line. We might then get lucky and might not need SMI at all.

Glenn, please attach the output of superio -Vd, we cannot proceed 
without that.

Glenn, please keep the list in the loop and do not break threads.

now, you said the chip read it8703f-a, but i seem to have a hard time 
digging anything out for this device. I for now am looking at the 
it8702f-a datasheet.

You were asked to attach the output of superio -Vd. This output, even 
though it doesn't directly detect your superio, will be sufficient for 
us to tell what is going on here. So please do so.

Glen his superio output (thread got broken again) revealed that his
IT8703F identified itself as 0x8701 0x0F on 0x2E.

Attached is a quick hack for superiotool that dumps the gpio registers 
(copied from ldn 5 of 8705) to this device at ldn 7.

here is a a few out the outputs since I don't know exactly what you are looking for but it took me so long to get superio working again I just took that chance to get ldn out puts up to 10 and down to 5 that we hadn't looked at already.

None of these seem to have valid information or the stuff we are looking 
for. Without a datasheet it then becomes really hard to find out exactly 
what is going on here.

Let's stop poking the superio and take a shortcut, where we just poke 
0x370 directly and hope for the best... Not the most ideal solution :(

Thanks for sticking with this though.

Ok, here it is... A first stab at a board enable... Not the way it 
should be, but we have little other option.

Glenn, apply on top of a clean flashrom tree.

Luc Verhaegen.

[Luc Verhaegen]

Another stab at a board enable, previous one was actually the board 
disable...

Glenn, please first svn revert board_enable.c

Luc Verhaegen.

[Luc Verhaegen]

Attached is the hopefully final patch for the board enable. Glenn will 
now test it with the boards original bios. If this succeeds, then we had 
two issues combined;
* board enable.
* something funky going on with the SST49LF040B that got hot-swapped 
into the place of the boards original SST49LF040.

Glenn, since you tested this successfully, can you reply with an:
"Acked-by:" statement?

Thanks,

Luc Verhaegen.

FW: Asus A7V8X needs a board enable.

[Glenn Mueller]

Acked-by: Glenn Mueller ([e-mail])

Erased and flashed successfully the factory chip for the board. Proved this to myself by flashing the bios for my 650i machine onto it and taking the off chance it would boot from it... it did, a hot swap and an awdflash later my 650i is operational again on its factory chip and reflashed the a7v8x with its factory bios too. Good news is it worked perfect. E-mail sent from the 650i even :) Let me know if you still want to try and make the a7v8x flash the other chips or if it doesn't really matter.

Thanks, -> r652

Ok, so flashing worked on the sst49lf040b in the 650i?

Have you tried setting the board enable on the a7v8x with the 040, and 
only inserting the 040b after this, when the WP and TBL have been raised 
already?

Luc Verhaegen.

FW: Asus A7V8X needs a board enable.

[Glenn Mueller]

Yes the sst49lf040B came from the 650i and once i got a good boot out of the chip from the A7V8X i was able to hot flash using dr-dos and the factory program. That is only a working solution if your board boots. Tried enabling with factory chip then swapping to flash it still gave the same error. I am more surprised to see that the 650I booted from the sst49lf040, just for grins i ran the flash program on the 040 to see what it detected it as... a sst49lf080A?
Oh yeah I found an old file I had lying around it it is supposed to be the full 2 meg award vanilla bios. I thought you guys may be interested in it contains alot of files but requires assembling etc before flashable. I haven't been able to do anything with it yet I got it when I was looking to make this 650I run a 45nm cpu... I don't think I can :) Anywayz it is up for grabs.

Aha, so you flashed using another program. Can you try flashing the B 
variant using flashrom in your 650i board?
