Installing KYBD.BUF is automatic when you type INSTALL {drive}:
This is covered in README.1ST.
KYBD.BUF has five switches that may be set at bootup time (if you don't like
the default values) by putting them on the line DEVICE=KYBD.BUF in
CONFIG.SYS. BE SURE to leave a blank space after "... .BUF", then put
a "/", the first letter of the command, and the number to which you
wish to set the parameter. For example, the line:
DEVICE=KYBD.BUF /b35/R3/V1/W1
^ blank space
will set the keystroke buffer size to 35 (/b35, default is /b48), place
the buffer window on line 3 of the display (/r3, default is /r1), opens
the window as soon as KYBD.BUF is loaded (/v1, this is the default),
and attaches the code and storage for a warm boot (the default is NO
warm boot).
* /Bn, n = 15 to 255, sets the maximum number of keystrokes held in the
extended keystroke buffer
* /V0 closes the view-port to the keystroke buffer on bootup. The
view-port may be reopened by pressing KEYPAD 5, V after PKII.MOD has
been loaded (unless the /N1 switch has been set, see below).
* /Rn, n = 1 to 25, tells KYBD.BUF what line on the display you want
the WINDOW to appear.
* /N1 disables the view-port and warm boot, and replaces that code and
storage with the buffer contents. This saves 112 bytes (382 bytes if
warm boot was attached).
* /W1 attaches the code and storage necessary for SCROLL LOCK, F1 to
perform a warm boot. Normally, it is not attached.
IF you have chosen to use the view-port and attach the warm boot code and
storage, KYBD.BUF uses only 398 bytes, plus twice whatever length the
buffer is. KYBD.BUF will operate just fine whether POWERKIT II is
loaded or not (but then, its fast warm boot routine would have to be
accessed by a far jump to offset 0Eh in KYBD.BUF's segment)
NOTE: The luxury of POWERKIT II's extended keystroke buffer may have to be
foregone in some cases. Unfortunately, some programmers think the only
buffer the BIOS (Basic Input Output System) supports is the small buf-
fer at 40h:1Eh. Their programs use this buffer exclusively, thus ig-
noring the buffer whose dimensions the BIOS reads at 40h:80h. You will
know when you encounter such a program and POWERKIT II's buffer is set
to more than 15 keystrokes, because your machine will hang and not even
KEYPAD 5-ESC (described in PKII.DOC, page 6) will save you, and POWER-
KIT II's fast warm boot (SCROLL LOCK-F1) will just put you back in the
same fix.
