Starting slackware installer via grub2

I have a 16GB flash drive with grub2 installed on it so I can boot Linux iso's in place of burning 200 CD's. I looked at the isolinux.cfg file and came up with this:

Code:

menuentry "Slackware 13.1 64bit" {
	linux /boot/slackware/13.1/64-bit/bzImage initrd=/boot/slackware/13.1/64-bit/initrd.img load_ramdisk=1 prompt_ramdisk=0 rw SLACK_KERNEL=huge.s root=/dev/ram0
}

However the kernel panics because it cannot mount the root file system. It gives me the options of using my partitions. What should I put for the root parameter?

Did you try setting root to the partition that holds the iso?

I just would use

Code:

menuentry "Slackware Install" {
	insmod ext2
	set root='(hd0,1)'
	search --no-floppy --fs-uuid --set 67655dbc-a9ca-4faf-abe6-2c05d92a30a1
	linux /kernels/hugesmp.s/bzImage initrd=/isolinux/initrd.img load_ramdisk=1 prompt_ramdisk=0 rw SLACK_KERNEL=hugesmp.s
	initrd /isolinux/initrd.img
}

where the blue is put the UUID number of usb
do "blkid" as root to find out UUID

maybe be better too to just put the kernel in /isolinux folder also and change path
linux /isolinux/bzImage

Code:

menuentry "Slackware 13.1 64bit" {
	insmod fat
	set root='(hd0,1)'
	search --no-floppy --fs-uuid --set 1F1D-B128
	linux /boot/slackware/13.1/64-bit/bzImage initrd=/boot/slackware/13.1/64-bit/initrd.img load_ramdisk=1 prompt_ramdisk=0 rw SLACK_KERNEL=huge.s root=/dev/ram0
}

Same problem. Can't mount root. I started a Virtual Machine to boot the iso I had made and ran "mount", nothing is listed as mounted at /

*Edit*

I got it working with this:

Code:

menuentry "Slackware 13.1 64bit" {
	insmod fat
	set root='(hd0,1)'
	search --no-floppy --fs-uuid --set 1F1D-B128
	linux /boot/slackware/13.1/64-bit/bzImage initrd=/boot/slackware/13.1/64-bit/initrd.img load_ramdisk=1 prompt_ramdisk=0 rw SLACK_KERNEL=huge.s
	initrd /boot/slackware/13.1/64-bit/initrd.img
}
