EPIA flash questions

[Joshua Wise]

Hi folks,

Well, I finally got myself a Linuxbios supported board (an EPIA 
ME-6000). Later tonight I'm going to order a flash from Mouser to swap 
out, but before I do, I have a few questions:

On board is a PLCC form factor 39SF020A. Mouser also carries the 
39SF040A, which is a 512k ROM. The pinouts seem to be the same, but I'm 
not sure whether the extra address lines are carried out anywhere. Does 
anyone know whether the EPIA will be able to use the extra 256k?

Also, I was not planning on getting a BIOS savior. Does anyone have 
experience with hotswapping flashes on the EPIA? Will bad things happen 
if I do? Do I need to make myself an external board with chip select 
lines, or can I just hotswap?

Thanks,

joshua
