I have two hdds, the first hdd that I use as master is my Win XP hhd and the other one that is slave is using Slackware.
The Win hdd is named IBM something and the Slackware hdd is named WDC. When I boot the computer normally (no boot options) the Windows XP hdd starts fine. Then I reeboot and press F11 and the boot menu appears. I choose the WDC (slave) in the boot list and then the Linux hdd starts, I get the LILO red screen thingy and just hits enter.
When Slackware is doing its thing in the start I suddenly get a error messgae that says: can't find reiserfs on IDE0, or something like that.

The IDE0 is my Windows hdd that is NOT running at the time.
Maybe Slackware thinks that it should run that hdd and then something happends Maybe I should type something in the LILO boot screen?

btw, the Windows hdd cant run as Slave under my Slackware hdd. I get the error message "HDD slave error Press F1 to resume"
I dunno y that appears but I dont care since it really doesnt matter for me wich hdd is master and slave.
