Description

  • Add support for PAE and more than 4 gigs of ram on x86, dependent on the kernel opition 'options PAE'. This will only work with device drivers which either use busdma, or are able to handle 64 bit physical addresses.

Thanks to Lanny Baron from FreeBSD Systems for the loan of a test machine
with 6 gigs of ram.
