I have an VIA EPIA CN13000G board , and bought five SST49LF008A chips from internet.
I'm afraid those chips can not work on that board.
No EEPROM/flash device found.
Also i tried to flash original BIOS rom (SST49LF004B), it work fine (read/write). So what did i miss? Could someone tell me what to do ?
I believe your original chip is SST49LF040B, not 004B. 004B and 008A understand only Firmware commands (they are FWH-compatible) while 040B and 080A respond to "LPC Memory Read" commands and are called LPC chips.
I suggest trying to find SST49LF080A-33-4C-NHE chips instead.

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 ?
