There is 440BX code in LinuxBIOS v1 that should be working, but I
don't know if anyone has tested it for quite some time.

There is currently work being done to port the 440BX code over to v2,
but this has proven to be a bit of a challenge.

This seems to be supported in LinuxBIOS v2 already.

Slot 1 isn't explicitly supported, but PGA370 is so it will probably
work out fine.

W83977TF is supported, but there is work also on boards with EF. The
two are very similar so this should not be a problem.

Yep, this is supported in the flashrom utility.

Overall you're in pretty good shape, except for the critical central
440BX northbridge. :)

Not completely supported today, but perhaps in the near future.

The 440BX has been said to be working in v1.

Uwe has created/ported into a tyan/s1846 tree in LinuxBIOSv2.  The S1846
is a 440BX board but it has a different SuperIO.

So I've created a patch replacing the tyan/s1846 SuperIO with the
W83977EF SuperIO chip code.

Really simple... but..

I'm stuck here trying to get console_init.

W83977EF is said to be working in LinuxBIOSv1 tree, but an earlier
W83977TF released chip was ported over to LinuxBIOSv2.  Basically,
they're basically the same chips so it's just a matter of resolving an
address conflict.

You can google for "W83977 linuxbios" and you'll pull up some good info.

And, console init seems to be really the only problem as my bios
postcard shows the linuxbios rom image loading and executing quite
happily to a point well passed where console init should have been
enabled.

This was just added (or has been in) util/flashrom

I haven't posted any linuxbios rom images for this W83977EF as I've yet
to get console to init.  But, I've posted a patch here:
http://www.eskimo.com/~roger/files/linuxbios/440BX.P2XBL/

or, top page where you can see the 440BX boards I own.

http://www.eskimo.com/~roger/programming/linuxbios/index.html

Really, the northbridge problem seems more trivial then a big issue.
IMO, it's just a matter of finding what is missing or isn't working in
v2 and why v1 works.  Could be tomorrow, or soon. (hopefully ;-)

Not for this exact mainboard, but I tested the Tyan S1846 recently, and
RAM init _seems_ to work fine on this board (didn't test anything else).

Unfortunately the information in the wiki was wrong, I fixed it. There
is some code to enable SMBus, but other things like IDE, PCI, LPC, and
whatnot are not supported, yet.

I'll fix this later, expect some patches "soon" :)

Uwe.

This is what I thought as I examined my own ckermit logs.  Memory looked
fine... no obvious errors spawned.  But errors when PCI was initiated.

(I was thinking the PCI errors were spawned due to memory init invisible
errors from others talking on this list.)

Feel free to post some experimental patches or send them to me directly
and I'll try on my similar S1832DL.

Just an FYI.  I've been grepping my email and still remembered this
post.

This motherboard is partially working now with asus/p2b profile.

Just note, this is a W83977EF-AW & not a W83977TF, but differences are
minimal.
