does stefan put the mptable in first 1K?
good way is put mptable 0xf0000:0x100000.

MPTABLE in LinuxBIOS is put from 0x20, if the system has too many cpu and devices (slots) the mptable will get bigger than 0x464, so it will use 0x40:67....
Then you or someone moved it. The base in low memory was originally at 0x500, to avoid just these kinds of problems.
We need to put mptable to [0xf0000:0x100000] together with acpi tables.
Or move it up a few bytes.
and if it is bigger than 64k, then we have to put it on special postion ...from 1K, and pass the posstion of mptable to the kernel via command line.
I will update the code in LinuxBIOS.
Thanks. It is always a good idea not to assign legacy regions of the address space new meanings.
