Is it possible all the SST49LF008A chips are broken ?
SST49LF004B is LPC/FWH, but SST49LF008A is only FWH [1], the former was the stock chip on my board as well. I'm currently using a Winbond W39V080A with my board, a Jetway J7F2, or the SST chip Peter mentioned should work too. -Corey [1] http://www.sst.com/products.xhtml/serial_flash/49/SST49LF004B
