I realize that the S1846 is quite an "antique" and it would seem support for it was dropped during the LinuxBIOS 2.0 development phase. Code support seems to be in "FreeBIOS Devel. v1.0 Base0.tar.bz2" which I have archived; I can see from old lanl.gov mailing list archives I googled where Ron Minnich merged hcyun's changes into the source tree on 28 Sept. 2001 (yes, that how ancient this is!).
What's unclear to me is what version of the kernel source code might have ever worked with FreeBIOS when it supported the S1846 there for awhile under v1.0. I know the 2Mbit flash is too small for a kernel (that same message thread was in relation to an Etherboot payload originally), but I know a matching kernel source will be important nonetheless. Could I probably get away with trying 2.2.19 or 2.4.10, since they are dated closest to the time S1846 was merged into FreeBIOS v1.0 back in Sept. 2001? Or does anyone here (perhaps Yinghai Lu, who seems to have an excellent memory for all the Tyan board matters!) remember what kernel source version would have worked?
I've scoured all our spare & decomissioned systems here, trying to find something more modern that's been on the supported list at some point, but unfortunately this board seems to be all we've got. I'd like to be able to lab this out, which might convince folks to buy some newer Tyan's for this purpose, but for now I'd greatly appreciate anything the community can render in terms of advice.

Thats a 440bx based board. So the V1 Bitworks/IMS mainboard code should work if you fixup the superIO.
I've booted lots of different kernels starting from 2.4.3 or so up to 2.6.10 on the IMS board so I think if you just pick the latest and try you should not have any problems.

Good timing. Just last night I pulled in my V2 440bx framework patches into the latest SVN and began work on trying to make an Asus P2B work (Another 440bx board)
Currently I have the Asus up and spitting data out the serial port.
The V2 440bx stuff has a problem that I'm doing something wrong in the SPD read from the memory. It always returns 0xff.
The Asus is further complicated in that it has a something different with the spd bus that has to be enabled. The V1 440bx code does not work with the Asus P2B.
If you are interested in helping me work out the problems with the V2 440bx SPD read then let me know and I'll commit my 440bx V2 framework.
