It should be "make bzImage;make modules;make modules_install;make

Did you create a new initrd image?  You need to if you're using SCSI
and/or ext3 filesystems.

	# cd /boot
	# mkinitrd -f -v (kernelversion).img (kernelversion)

replacing "(kernelversion)" with your actual kernel version.

The above line is a pretty indication your initrd isn't there.
