Hi Peter ,
I had checked the original BIOS chip again, it's SST49LF004B,
and the flashrom output:

# ./flashrom
 Calibrating delay loop... ok
 No LinuxBIOS table found.
 Found chipset "VT8237": Enabling flash write... OK.
 Found board "VIA EPIA-CN": Enabling flash write... OK.
 Found chip "SST SST49LF004A/B" (512KB) at physical address 0xfff80000

any ideal? Is it possible all the SST49LF008A chips are broken ?
