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 ? -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
