sometimes it can be due to a mismatched configuration, most BIOSs (Award/AMI dont think phoenix tho) have the option for the mode LBA/LARGE/NORMAL depending on how the drive is set there, if the drives on the primary controller are set to LARGE and the ones on the secondary set to LBA it can cause this, although ive never seen it cause a problem. nate ----------------------------------------[mailto:[EMAIL PROTECTED] ]-- Vice President Network Operations http://www.firetrail.com/ Firetrail Internet Services Limited http://www.aphroland.org/ Everett, WA 425-348-7336 http://www.linuxpowered.net/ Powered By: http://comedy.aphroland.org/ Debian 2.1 Linux 2.0.36 SMP http://yahoo.aphroland.org/ -----------------------------------------[mailto:[EMAIL PROTECTED] ]-- 3:48pm up 182 days, 4:06, 2 users, load average: 1.01, 1.03, 1.00
