Hi all.

I'm having the same problem on i865+ICH5.

Registers 0xf4 on device 0 and 0x48 device 6 are "Intel Reserved".

From serialice:

Then it just sits there/hangs -- it is supposed to get to ram init.

The post code sequence is, with 99% certainty, like this:

68, b6, d2, d5, 0c,
2a /* only visible when soft rebooted */,
38, 3b,
84 /* busy with ram init/ram testing */,
60, 78,
a7 /* ? */,
a9 /* ready to load stuff from cd/harddisk */,
q9 /* ? */,
j0/00 /* not sure about j0, sometimes certain digit seems to be underpowered */,
e3 /* seen during the booting of linux */
00

SerialICE and gdb logs are attached, ask away if you need more output.
