You didn't mention whether you were using lilo or grub to boot. |

If you're using grub you can use the grub shell to figure that out. At |
18 |
least to the which are detected and numbering phase. |

I had that problem or something similar some time ago when updating to |
21 |
the new, at the time, pata drivers. I ended up using a brute force |
22 |
technique... I booted grub to it's built in shell and used it's limited |
23 |
tools to figure out which partition/drive was which and editing the |
24 |
kernel/initrd lines to get the system to boot to init level 1 and then |
25 |
make the changes permanent in grub and fstab. |

Probably an easier method would be to use a livecd. Just edit the grub |
28 |
menu.lst file and fstab to match your new layout. Or change the |
29 |
device.map to match the old layout. |
