Fai, unfortunately, the location of the flash transfer buffer was hardcoded in current releases. It's fixed for the next release to be at the top of RAM. If...

Andy, Are trying to verify that the product ID is 08? You should just look it up on the data sheet if you have it. SST's on-line access to full data sheets...

The flash ID is read by the pilot BIOS before the BIOS is even compiled, so those IDs should be at 4006-4007h regardless of what the BIOS does if compiling to...

Mar 5, 2001 10:04 pm
Andy, The initial loader (coldoader.bin) sets waitstates to 4 then loads the pilot BIOS to RAM, the pilot BIOS doesn't change any MMU/MIU settings. After the...
