Tyan S2915 OEM / HP xw9400 now supported

[Carl-Daniel Hailfinger]

Hi,

flashrom should work fine since version 0.9.2 revision 1008 on all Tyan
S2915 OEM boards.
The reason for the failing access was that those boards have two MCP55
LPC bridges. flashrom enabled the first LPC bridge (oddball PCI class)
instead of the second one (ISA bridge PCI class). Since we don't have
any reports of PCI ID 10de:0361 being used as "real" primary LPC bridge,
we blacklisted that ID for now until class checking is in place (which
may break on other boards with buggy BIOS, not sure). The "real" LPC
bridge on this board has the PCI ID

I'd appreciate full output of
flashrom -V
with latest flashrom (at least 0.9.2-r1008).

Thanks to everyone who tested and provided lspci output.

Regards,
Carl-Daniel

flashrom -v output attached.

Hi

this works fine !

flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
No coreboot table found.
Found chipset "NVIDIA MCP55", enabling flash write... OK.
This chipset supports the following protocols: Non-SPI.
Found chip "SST SST49LF080A" (1024 KB, LPC) at physical address 0xfff00000.

hi !

i tryed to flash a tyan bios but he was 2kB longer from the bios that i read with  flashrom.

I use dd to make it fit in 1MB.

But now i can't flash because there is a write protection.

On a forum i have seen that you should link pin 7 and 32 of the rom chip.

this disable write protection.

So flashrom was able to write, but did stop at 0xF000.

Now my motherboard dont boot anymore.

I'am buying a chip + a plcc32 socket on ebay.

I will try again when i receive the chip, because it is very interessant !

Read of bios work very well, write not because of the write protection.

You wouldn't have needed to do that, if you applied the patch from
http://patchwork.coreboot.org/patch/1426/ (very recent).
> So flashrom was able to write, but did stop at 0xF000.

Because your chips has *two* regions. The main region is 0..0xEFFFF, and
protected by pin 7 (#WP), while the boot block region is
0xF0000..0xFFFFF and protected by pin 8 (#TBL - Top Block Lock).

On the HP xw9400, #WP can be controlled by software, and the patch
mentioned above disables write protection using pin 7. I just committed
the patch as r1025. On the other hand, #TBL (pin 8) can not be
controlled in software. There is an unpopulated Jumper position on your
mainboard, next to the fuse F2. If you short these two pins (or connect
pins 8 and 32 of the flash chip), protection of the boot block is
disabled.
> Now my motherboard dont boot anymore.

That's because flashrom left the main block in an erased state when it
found out that the boot block can not be erased. When you had to cut
your BIOS, it's most likely Phoenix. You have chances that you can
recover if you connect a USB *floppy* drive (or an internal one, if your
board supports it) and put in a very special Phoenix Crisis Recovery
Disk. An USB flash drive does not work.

Hi!

I tried the same thing. I was able to write the Tyan BIOS (with the
'dd' trick). However, sincen aparently the boot block is write
protected, I get some system write errors on boot, and it takes an
awful long time to boot. But at least it boots... I tried flashing the
old xw9400 BIOS back with no luck. This is the error I get:
http://flashrom.pastebin.com/KNNiTJ0x

It also sees that I get some problems with the SATA-controllers, but
that might be related to the BIOS not functioning properly I guess.

[PATCH] Add coreboot IDs to make manual selection of HP xw9400 possible

[Michael Karcher]

Hi Nilse-Helge,

you experience problems trying to flash back to the HP BIOS, because with
the original Tyan BIOS, flashrom is unable to detect you have the HP OEM 
version of the board. This is why flashrom does not remove write protection
anymore. The attached patch adds a coreboot ID for the HP xw9400 board, which
makes it possible to tell flashrom you are on an xw9400 from the command line.

After applying this patch, run

flashrom -m hp:xw9400 -w hpbios.bin

This should return you to the original HP BIOS if the boot block write
enable jumper is shorted (the two pins next to F2), or bring you into    
big trouble if the boot block is still write protected.

Regards,
  Michael Karcher
