And also a DIP->PLCC adapter so you can use it for the SST part?
If you have one or can make one this is your best bet. I'd recommend
using the standalone programmer if at all possible.

I'm not an expert on uniflash but it could have limits on flash size
or require some particular checksumming algorithm to be used on the
binary file and have a checksum in a special byte offset to consider
the flash image valid, or maybe it checks this checksum on write
verification so verify fails unless the checksum is correct, etc.
Note that this is only speculation and wild guesses.

If uniflash or the Abit board is limited to 512KiB ROMs verification
will (should) always fail - so maybe this is a matter of the chipset
not decoding more than 512KiB to the LPC bus. This feels more likely
than crazy, damaged code in uniflash.
