The DMA being related to a parallel printer issue is interesting. Don't see how it could be related.
Some bioses allow to set the printer port in "ECP/DMA" mode, in which DMA is used to transfer large quantities of data from memory to the printer port with no CPU intervention. It is also interesting for external disk drives plugged to that port, but I have never had luck with it (Iomega zip). The other method of using the port with an interrupt assigned seems to work better, but uses some cpu (but much less than the default polling method). Read Mr. Johannes post on this, it is very interesting. - -- Cheers, Carlos Robinson -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) Comment: Made with pgp4pine 1.76 iD8DBQFDcli3tTMYHG2NR9URAnCNAJ9H7/xkM5EdhOxwdujtOpN/QarbVACdE6GJ eLNHcRzsSkuONAEdyx6m9Jo= =I4Pf -----END PGP SIGNATURE-----
