moving printer IRQ

[Bill Mulert]

On a stock SCO Xenix 2.3.2 system, the line printer driver is
configured to use IRQ5. In order to free up IRQ5 for additional
hardware, I need to move the printer driver to IRQ7. When I
edit the master file, and change the pa entries for vec1 and
vec2, I get a kernel that fails to boot. I have tried setting
vec1 to 7 and vec2 to 0, and vec to 0 and vec2 to 7. No deal.

Can anyone advise me on how to free up IRQ5 but still have an
operational printer driver?
