Unhappy Help needed : Dual booting of Linux 8.0 after system upgrade

Here is a typical problem I am facing in my machine. I have a intel P4 machine having Windows 2000 professional and Linux 8.0 installed in different partitions. I am using Win2000 boot manager to boot Windows as well as to start LILO (installed on 1st sector of / partition) and subsequently boot Linux 8.0. My system was working perfectly till I upgraded my RAM and replaced the CMOS battery. Now Windows 2000 is booting perfectly but getting problem while trying to boot Linux. Its giving me message "Kernel panic : Unable to mount / file system" . BTW, I haven't done any modification in the contents of any of the harddisk partitions.

After a careful investigation I found the following observation:
1. My hard disk partitions, which were earlier getting recognized as /dev/hdc1, /dev/hdc2 ... etc. are now detected by the system as /dev/hda1, /dev/hda2 ....

Is this the problem, why my system is unable to boot Linux ? Why this has happened ? Is this because some connections between hard disk and floppy drive are interchanged ? What is the solution for the same ?

Shouldn't be that easy to interchange the drives, but I guess it can happen. The main thing is to make sure things plugged into the place they were plugged into before. For instance, if your linux drive was on /dev/hdc, and now it's on /dev/hda, not much is going to work, because a lot of the links are going to be looking for files on /dev/hdc. As hdc is your first drive on your secondary ide bus, you can just swap them back to where they were before, and it should work. It's probably just the hard drive cables, because floppy cables are usually a smaller connector.

On an amusing note, my sister recently did something similar. Not with linux, but with her car. She changed her own spark plugs, then just plugged the wires back in however she felt they went. Two were backwards, and needless to say, the car was sputtering like heck and wouldn't stay running. Not a big mistake, but it's those "easy" things that tend to make life so much harder.
