Hi All,
My machine began life as a box standard IBM Aptiva 2142-
S46 PII 266 with 32Mb RAM, 4.2 Gb HDD (Now PII 333 with
384 Mb RAM, 20Gb HDD).
I have done a trial installation of XP Pro on my spare
HDD, and the system is mroe stable with XP than it ever
has been with any other OS. However I have a few problems..
Can anyone tell me how to:
A) Acitvate the power amplifier for the integrated
speakers and subwoofer. (These are driven by an on-board
Crystal Semiconductor CS4610 / CS 4236b Soundcard, through
a small off-board bespoke power amplifier, connected to
the system board via a ribbon)If I plug headphones into
the jack socket on the system board (bypassing the power
amplifier), the sound through them is normal - so the card
itself is functioning normally. Also, I can activate and
deactivate the power amplifier at will in DOS mode; and if
I cold boot using the IBM Diags and Utils CD, then warm
boot to Win XP the speakers function... but how to get
windows to merely "switch on" the power amplifier
automatically, so far escapes me.
B) The volume control on the monitor is another problem.
This is software driven, and acts upon the volume control
(sliders) within windows through one of the sound driver
files... but which one .. and how ?
C) IRQ steering is not functioning. Windows says that it
is unabe to find an IRQ table for the system board.
D) Unable to install driver for the keyboard shortcut
buttons - this in itself is no great hardship, the only
feature I'd use with any regularity is the stand-by (or
suspend) button.
Unfortunately most or all of these problems are due to the
fact that the standard driver for this PC aren't
compatible with Win XP.
The original operating system was Win 95.
Does anyone have any ideas please ?
