After the POST, but before the 9836C looks for an OS
to load,
it emits a series of high and low pitched beeps (low, low,
high, low, high, high, low). After that, it is able to load
an OS (HP BASIC) and run fine, with the exception that the
left-hand floppy drive is inaccessible.
Here's some "useful" information from my 9836 manual under the
heading
"Boot ROM Beeper":
"In addition to displaying an error and waiting a minute, the Boot ROM
4.0 sounds a pattern of beeps. The boot ROM is actually sending an
error message to a service person. If this error pattern is sounded,
check the display for an error message. If the message indicates
something you cannot correct, or if the display is not working, you
should call HP for service. Your service representative may ask you to
restart the self-test so he can listen to the error code sounded."
So, I conclude that the audible error code means nothing more than what
is printed on the screen and is sounded in the event that the display
isn't working.
