'Found the problem with the Lexmark Z52 printer driver. Maybe someone here knows how or "why" this happens. The driver sends output to ghostscript. All was working perfectly, UNTIL I attempted to change res. IN StarOffice. The driver that you MUST use in S.O. is the "generic" printer. I attempted to change setting in S.O., instead of using the Lexmark util. It worked the first time, but the next time I went to use the Lexmark util., "nada!" I was stuck at the last setting I used IN S.O. The "cure" was to reinstall ALL of my ghostscript files using Yast1. As long as you ONLY use the Lexmark util. to change any settings, all is well. I'll also pass this info. on to Lexmark. Fred -- If you listen on a quiet night, you can hear the sound of an NT Server reboot.

Does anyone have a K7V system running well? If so, what is your transfer rate and what are you using? Is there a specific kernel upgrade/patch I should install? Also, what is the correct processor selection when compiling the kernel? Athlon or K7 CPU is not specifically mentioned. The system runs very well otherwise. I really, really didn't want to go with Big Bad Intel, because of their nasty practices like inserting privacy-invading serial numbers without telling anyone, and buggy chips. Thanks for any tips in advance. 73, Brett Ottawa, Canada

Have you tried any of the following? hdparm -c1 -d1 /dev/hda or even better hdparm -c1 -d1 /-X66 dev/hda Be warned the -X66 does cause problems with some drives... -- Mark Hounschell markh@compro.net

Well, now that worked just fine: 22 MB/s+. Thanks. Don't know why this wasn't working before. Must be sunspots ;-)
