to "options FFS_EI". The superblock and inodes (without blk addr) are
byteswapped at disk read/write time, other metadatas are byteswapped

by userland utilities.

The other copy, phys_seg_list[], starts out with all of physical RAM (and

actually managed by the VM system.
- Fix computation of physmem; when support for MACHINE_NEW_NONCONTIG was

located before the kernel, or the memory taken up by the kernel itself.

when considering attaching compatibility-mode channels, try a quick reset
...
and see if anything responds. if nothing (that's attributable to the
PCI IDE controller) responds, then that channel either has no devices on
it or has been disabled (via a non-standard mechanism) by the BIOS. If nothing
responds, don't map the compat.-mode interrupt or attach the wdc to that
channel, because the BIOS is likely to assign that IRQ to a different PCI
device. If that happens, the kernel will panic because that device will
try to map the IRQ level-triggered, but the compat interrupt will have been
mapped edge-triggered. (One possible way around this is to map the compat
interrupt edge-triggered, but it's not clear reading the spec that this
is correct or desirable.)
