PC Locks Up When Printing from Pentium

PC locks up when trying to print a format from Windows version 1.2 or 1.3 or when trying to access printer status from the print queue.

IRQ conflict, hardware conflict on the Pentium. It's possible that the serial card's buffer is not being cleared.

1. In the system's ini file include the following line in the [386ENH] section:
COMIRQ SHARING = TRUE
COMXFIFO = 0 (WHERE X IS THE COM PORT NUMBER)
For example, if the printer is attached to Com 2, then the line should be:
COM2FIFO = 0

PC locks up when we try to 'test print' a label from the edit menu or from the print menu. Need to reboot the PC.

Possible problem with the type of display driver that is used. Specified display driver was a Mach 32.

We changed the display driver to VGA and all seemed to work fine.
