Why don't linux-2.1.75 image boot?

I made a kernel image (bzImage) that was configured and
built the linux 2.1.75 that had been patched with
patch-2.1.76.gz, patch-2.1.77.gz, and patch-2.1.78.gz.
During configuring and building the kernel there was no
After replacing the old System.map file and configuring
our Bootloader (/etc/lilo.conf)
I reboot using the new kernel, bzImage.

However our computer is NOT REBOOTED.
Boot message at the point of stopping is as follows:
     Partition check:
     VFS: Cannot open root device 08:01
     Kernel panic : VFS : Unable to mount root fs on 08:01.
Root device is a /dev/sda1, and the device major number is
8 and minor number is 1.
I'm looking forward to reading your message. :-)...

After editing /etc/lilo.conf, did you run /sbin/lilo?

After editing /etc/lilo.conf, did you run /sbin/lilo?

Here's another way, probaly the best way !

Rebuild your kernel and copy the bzImage file to your /boot dir.
the go back to the /usr/src/linux and do make bzlilo, now it does everything itself, and it always work, reboot and watch !
