Largest BIOS Workspace

[Don Brown]

Within BIOS in general and LinuxBIOS in particular, what is the largest
workspace available.  Are we limited to a 4 meg chip to store LinuxBIOS?
Can we build or lever into some larger area?

Depends on your motherboard (primarily - how many address lines go to the BIOS 
socket?).

If you use banked architectures such as DoC then you can access much larger 
amounts of storage on a device plugged into that socket, however I'm not sure 
if that meets your needs (maybe you're looking for a simple contiguous memory 
space)?

you can take as big an area as you want, but you need a chip that big. The 
limit is the chip, not linuxbios.

also, 4 meg: you mean megabits or megabytes? Lotsa confusion from people 
on this ...
