1.0 NEW FUNCTIONALITY
The following new functions have been added to BOOT:
1. Subdirectory handling. BOOT will now load/dump
from/to a subdirectory.
2. Dual-port unlocking. Previously, BOOT would
unconditionally grab a dual-ported RP04567 and not
release it until the load or dump was completed.
Now, it is more polite, locking and unlocking the
port for each IO transaction. This allows the
other system to access the device when the port is
unlocked. In particular, one can now interrupt a
load or dump in progress with ^\ and get to the
RSX20F parser. A single ^\ is sufficient (it
requires about 2-4 seconds to receive the parser
prompt).
3. Single-pass loading. BOOT will perform only a
single pass to load release 6 monitors. It will
still perform a 2-pass load on pre-release 6
monitors.
4. Long-file handling. BOOT can now load a monitor
containing more than 512 pages.
