yes, no errors with SparQ or the printer...however...

I certianly _certainly_ didnt get the message above (or anything approaching it)
eitheron my root terminal or via dmesg (or /var/log/messages) ....infact..nothing...
the chipset is a National Semiconductor PC87338, i have gone to the national
web page and requested the tech ref paper. It certainly seems to be some sort of
between the chipset (maybe its not being initialised properly under linux ?) or else
bantam cdrom drive talking to it (the other suspicion is that they have done
strange, to the handshaking.)
I dont really see how it could be the negotation phase, as it does claim IEE 1284
hurmm...maybe i should have finished my degree in micro-electronics ;)

it is most certainly the PC87338. i have looked at the chip markings on the laptops m/b
(no easyfeat, it was stuck way up at the back under a largish heat plate :).

this brings me to another question (dumb as it is ;) could the 20x be a scsi cdrom
drive ? i seem toremember hearing that the bantam 24x was/is ....would paride fail
before the error its giving out if it
was a scsi and not atapi. The box (and web site) very helpfully dont mention a thing
