[zhu shi song]

Hi, 
  (1)A6T MB is based on via chipset vt8601/686b
  (2)IPL can successfully copy linuxbios into
0x8000:0000(I have read them out to test this point)
  (3)The first line of linuxbios is to output %al to
port 0x80
  (4)When IPL jumped to 0x8000:0000, the first line of
linuxbios couldn't be executed.  Halted.
   who have met such problem? please help.

tks
   zhu

try booting memtest86, I think your memory is wrong.

I have tested my SDRAM booting memtest86.  The memory
is OK.  Maybe vt8601 northbridge sdram init has
something wrong.
There is another question, how to setup the FSB of
sis630ET?  I've got ECS p6stmt MB based on sis630ET.
After reading the values of pci registers, its bios
have used synchronous mode of SDRAM.  I think
synchronous mode means FSB is equal to SDRAM clock. 
My SDRAM is 100Mhz.  So I must set MB FSB to 100Mhz. 
The default FSB of the MB on powering is 66Mhz.
