FWIW, I have been using the older VMware versions (up to 2.04) on
Mandrake systems, from the 2.2 to 2.4 kernels (currently 2.4.18, MD
8.2). I set my parallel port to ECP in the BIOS, and put the lines
alias parport_lowlevel parport_pc
options parport_pc io=0x378 irq=5 dma=3
in my /etc/modules.conf file. I believe that all necessary PP ECP
support is either compiled into the Mandrake kernel or available as a
loadable module, because I use the stock kernel and don't explicitly
load any other modules (other than the VMware ones of course). I then
set the parallel port in VMware to /dev/parport0
with 'bidirectional' checked. This allows me to use my PP scanner from
the VMware windows session.
