These symptoms have been observed with some parallel ports if they are
set to EPP 1.7 rather than EPP 1.9 mode. Check your parallel port
CMOS settings.

It does, but the adapter is not regenerating the ISA/IDE timing signals
quite correctly so the drive and the adapter lose sync with each other.

PARPORT gives you the ability to share parallel port devices on the same
port without loading and unloading the competing drivers (among other
advantages.)

PARIDE can be built to use or not use PARPORT. If it is built to use
PARPORT, then the parport modules must be loaded prior to loading the
paride modules.

The short answer is No. There is a much longer answer for brave souls
with nothing better to do with a few weeks of their time :-) You will
never be able to boot from it, however.
