I just used Uwe's Tyan S1846 tree and everything *just* worked. :-)
However, I don't mean everything worked.
I've attached a log file of the boot for those curious.

Known issue, I figured you already knew. Ram init is very much broken
on
the i440bx northbridge.
0xa0000 looks more like video memory to me.
try checking 0-0x9ffff and 100000-TOM
[Attached full log of LinuxBIOSv2 output.]
Error #1 of 2 (DRAM Succeeds):
Ok. I've set the following in tyan/s1846/auto.c:
/* Check 64 MB of RAM. */ /*ram_check(0x00000000, 0x04000000);*/ ram_check(0,0x9ffff); /*ram_check(100000,TOM);*/Should I try also (100000,TOM) or is it satisfactory once DRAM succeeds?

According to my searching via google, this looks to be about the current status of this board.
If the above DRAM memory search range is a custom that is related to this specific Tyan S1832DL, how about I provide an svn diff for inclusion into the tree? (If not, will just keep using s1846 tree and is preferable for further code updates.) -- Roger http://www.eskimo.com/~roger/index.html Key fingerprint = 8977 A252 2623 F567 70CD 1261 640F C963 1005 1D61
