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.

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

OK, this _looks_ good, but I'm not sure it actually works. Did you start from a cold boot (power-off)?
Results which you get from merely soft-resetting the system are not reliable.

No need for a patch here, I think.
What needs fixing is the code in raminit.c which is generic for all 440BX boards...

Yupper! Cold as in Cold Beer. :-)

Ok.
I've posted additional info about the 440BX boards I've test here onto my website, along wit a S1832DL prebuilt rom image for others to have fun with.
BTW. I like the WP1 & WP2 indicators for the website documentation on the chips denoting what needs work.

Couldn't we just provide an "IF ram_check failed, then provide This Location" within auto.c?
Or are we talking adding a feature for ram_check for checking alternate ranges as a fallback?
