Fixed disk controller logic (really disk timing logic) so that disk can run at 100% speed (rather than 50% speed). Changed endian-ness for ethernet packet words to match 3mbit bridge. (Similar changes also made to IFS). Removed some dead code.

Fixed remaining disk issues; KSTAT bits 4-7 must always be "1," and head select change must reload current sector. Boot now loads in complete boot program and control is transferred to it.

Fixed: Disk address (KADR) and Disk Data (KDATA) registers behave (more) correctly; in particular record commands hare processed properly and KDATA handles reads/writes more sanely. Fixed checksum calculation; due to above changes microcode now correctly validates checksums and boot progresses to read in an entire track's worth of data before dying with a "check failure" error.
