Josh Dersch a689b7185a 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.
