     The  password  program PASS.COM affords a modest  degree  of 
protection  for  users  of systems that boot from  a  hard  (i.e. 
fixed)  disk.  By  autoloading it on (cold)  boot,  you  make  it 
impossible to get around the password without  rebooting from the 
floppy drive (and you need a floppy with system tracks to do it). 
This  should  prevent casual pests from using your computer  when 
you're not around, although of course it won't stop the hackers.

     The password must be eight letters long, and can contain any 
printable  character (lower-case will be folded  to  upper-case). 
The  original  password is ...  you  guessed  it,  PASSWORD.  The 
enclosed file PASCH.COM can be used to change the password (don't 
leave it on your disk!). Or you can change it less elegantly with 
DDT etc. at 25F-266h.

     Autoloading can be accomplished most simply by using  CMDLN.
Or you can patch the CCP in SYSGEN, PUTSYS etc. &  then write the 
new  image  back to the system tracks of the hard  disk.  On  the 
Kaypro-10 the file is called PUTSYS.COM. The patch location is at 
987h, the standard location of the CCP on  all such programs.

987h --> 4 (number of characters) 
988h --> 50h (=P) 
989h --> 41h (=A) 
98ah --> 53h (=S)
98bh --> 53h (=S) 
98ch --> 0 (terminator)

The  same patch can be placed on floppies (it requires a copy  of 
PASS on each disk).

NB  -- On some systems a file autoloaded in this manner  will  be 
run at each warm boot.  The K-10 doesn't do this because the BIOS 
warm  boot routine zeroes the character count byte at  CCP+7.  If 
your BIOS doesn't do this you should patch it, unless you want to 
enter passwords all day long.
