New subject: Other RT-11 boots

30 Apr 1999

...
 Using a DEC RX01/02?  if not RT-11 format will NOT owrk
on the H11 disk. 
You must use the heath H11 formatter (or I think the switch must be in
RX01 mode).  In either case the H11 disk system is very different from
the DEC save for RX01 media compatability.  
Good point...

...
 Alsi did you "init" the disks?  the didks
need to be init'd to establish
the RT-11 directory.  The command in .INIT DXn: 
As we've been mentioning, V2C was too early in RTs life to have either
CCL or DCL, so there is no init command (which would run DUP, but there
is no DUP).  Running PIP and issuing 'ddn:/Z[/N:n]' is the correct way
to lay down an RT file structure on a volume which has been formatted.

Aha... found the problem with the boot command I gave earlier... it
should have been

	.R PIP
	*DX1:A=DX1:MONITR.SYS/U

*This* writes the bootstrap... /O actually does a boot.

Just for completeness, the options for V2C PIP (and I would suspect
V2B as well) are:

	/A	Ascii file transfer
	/B	Formatted binary
	/C	Only include files with current date
	/D	delete specified file
	/E	list directory, include empty space
	/F	list directory, short form (filenames only)
	/G	Ignore input errors during file transfer
	/I	Image mode (default)
	/K	For bad block scan, list absolute block numbers
	/L	list directory
	/M:n	File position for magtape or cassette tape
	/N:n	Number of segments (used with /Z)
	/O	Bootstrap the specified device
	/R	Rename file (new=old)
	/S	Compress (squeeze) device - not the same as a
		file compress, which encodes the file, this simply
		moves the files to the beginning of a volume, and
		all the empty space toward the end (remember, RT-11
		file structure uses contiguous files)
	/T	Extend number of blocks allocated for a file
	/U	Write bootstrap to volume
	/V	Print version number of PIP
	/W	Include absolute starting block number for directory
		listings
	/X	copy files individually without combining...
	/Y	Must be used to perform operations on .SYS and .BAD files
	/Z[:n]	Zero directory (with 'n' extra words per directory entry)
