treat all DMA reads/writes as kernel mode (previously it would depend on whether the processor happens to be in user mode or kernel mode when the DMA completes, which is totally incorrect); handle 32-bit accesses that straddle page boundaries properly (all 32-bit accesses are now split into two 16-bit accesses); allow reads to the entire zero page, rather than just address 0 andrew Fri, 18 Apr 2014 01:26:01 -0600	changeset files
disabled seek delay on WD2010 (Unix seems to work fine without it) andrew Thu, 17 Apr 2014 01:58:05 -0600	changeset files
ignore out-of-range addresses on low-level format commands (s4diag formats once sector past the end of each track) andrew Thu, 17 Apr 2014 01:50:41 -0600	changeset files
fixed bus error handling for real this time (save registers before every instruction and push the saved registers if a bus error occurs, since the instruction may have changed registers before the bus error, and also stop the instruction immediately with longjmp so it won't change memory after the bus error) andrew Wed, 16 Apr 2014 02:20:43 -0600	changeset files
