I was having some problems with my external CD-ROM drive(a sun-moon-star 8X CD-ROM drive), which plugs into a EPP printer port. I was trying to play MP3's straight from the CD, but was having little success. The MP3's would skip, and it really sounded like crap. I decided to disable the printer port on the WS, and enable the printer port on my ISA super I/O card to see if I would get better performance.
One thing that I noticed about my I/O card, is that it assigns a DMA to the printer port, while on the WS, there is no DMA given to the printer port.
The results are amazing. I can transfer files from the CD to hard disk at least 4 times faster, and MP3 CD's will now play straight from the CD-ROM without skipping.
Has anyone else seen anything like this with a parallel zip drive, or other device that uses the EPP printer port?
If anyone is planning on using a printer port device, I would highly recomend not using the printer port on the WS.
