- I'm not sure to which, if any, Packard Bell models this might apply,
- but there is a known incompatibility between Soundblaster cards and PCs
- which use an 82C710 chip (from Chips & Technologies) to integrate
- various functions (serial ports, parallel port, FD controller) on the
- motherboard. Creative Labs has a fix for this, available from their
- BBS as PORTFIX1.EXE (possibly PORTFIXn by now). This package contains
- a program (not a TSR) which executes once from AUTOEXEC.BAT to
- initialize the 82C710 correctly. If your PC uses an 82C710 and you are
- experiencing problems when a Soundblaster card is installed, it would
- be worth a try. Sorry, I don't have the BBS phone number.

- Actually, IRQ7 is the normal assignment for LPT1 for both XTs and ATs.
- IRQ5 is the default for LPT2. As long as you are using the parallel
- port only for printing, you should be able to use the same IRQ for any
- other purpose, since printer drivers generally do not use the interrupt
- feature of the port. If you have a SCSI translator or other exotic
- hardware hanging on the parallel port, however, you could well be in
- trouble sharing the interrupt.

-
- If DMA is indeed the cause of the Soundblaster incompatibility, the
- abovementioned PORTFIX1.EXE fix will NOT solve it.
