Re: SRAM Based PCI FPGA

Sorry you got this one wrong, Max is right. The HAL sets the base
addresses. There is a boot.ini switch /PCILOCK to indicate that the
addresses setup by the BIOS not be touched. I spent many a painful
day learning about this on a project where we had to get two machines
to boot identically.

PS. In general Linux is not a good reference on how NT or most of the
other OS’es on Intel platforms work.

No, IRQs and BASE addresses are most certainly set up by the BIOS. If you
set PnP OS=yes, then the BIOS may (often does) skip this mapping and leave
it to the O/S but NT in not famous for getting this right.
