Re: [linuxsh-dev] Back from the dead

Thanks for this. I wasn't able to test it before I posted as my
SolutionEngine has just been fried (the power supply was accidently
changed from 5V to 9V) and the Overdrive only has PCI I/O.

When I first did this work I only had one port2addr function. However I
got a bit confused by the code in the SolutionEngine io_se.c. There
appears to be different handling for PCMCIA I/O addresses (which doesn't
look finished...) and I/O to the SMSC SuperIO controller. I've never
played with PCMCIA, so don't really understand the issues, and kept
to two separate for this reason. If there is no good reason for this, 
great, I'll re-combine them.
