Yes - you'll need to get a flash chip to replace it.

Please check out http://linuxbios.org/FAQ under 3.7 how to identify
the flash chip package, and if the chip is socketed or not.

Worst case it's not socketed and then you would have to desolder the
current chip from the board and instead solder on a socket for a
flash chip.

Flash chips are easy enough to get hold of. It doesn't have to be the
same make - there are lots of compatible chips from different

If the soldering is needed and you're up for it there's a fair chance
you can get LB working on the board - but it does need some research
and experimentation to find some specific settings for this
particular board design that are usually different between any GX1
board - code supporting the hardware chips is already done though.
