Hi,
Thanks for the info. I've been looking at the Tyan Tiger MPX (S2466). What is Guiness referring to?
It was a code name of the Tyan S2462.
Might a comparison of PCI config registers or MSRs after OEM BIOS init and cold boot reveal something? Power management actually helps, since all registers must be read/write (as opposed to write only - like VGA Pallette snoop) so PM can save context on suspend. Does LinuxBIOS go far enough to get the serial port working?
I suspect more than anything the warm reboot case is more luck than anything else. I remember there are some checks in the code that will skip a practically all of the early setup in assembly if the machine is already operational.
I'm going to buy a board, is there any chance it can be done without an ICE?
I haven't used one yet...
And we currently have a mostly working port, though I don't know where we are on the release cycle for that.
From what I have seen of it the differences are almost totally due to the
different southbridge. The AMD2466 vs AMD2468.
