Description dhds_cell 2000-01-19 16:10:52 UTC
When I installed the out-of-the-box kernel and installation configuration
on my Pentium pc, it was not possible to write to /dev/lp0, or whatever
should be mapped to the very standard pc parallel port...
It turned out that kmod only loaded parport_probe, lp and parport.
parport_probe was not able to find the pc parallel port.
It turned out that putting "alias parport_probe parport_pc"
in /etc/conf.modules solved the problem. parport_pc now successfully found
the parallel port and it could be written to.
I think that this is a big deficiency in the standard Redhat 6.1 kernel
installation that should be fixed. I believe a significant number of the
6.1 users has a standard pc where the parallel port only can be detected
by parport_pc. By comparison, the S.u.s.e 6.1 with kernel 2.2.5 correctly
loaded parport_pc for successful parallel port detection.

Comment 1 dhds_cell 2000-02-03 11:02:59 UTC
I found that setting the following in conf.modules is better because it will
also enable parport probing:
alias parport_lowlevel parport_pc
#host dependent option
#options parport_pc io=0x378 irq=7

Fixed in latest beta of the installer.
