Have a look at the following manpages: boot(8) loader(8) This explains the FreeBSD startup system. In short, you tell the loader which kernel to boot, and you tell the kernel where the root filesystem is. The root fileystem is considered to contain instructions on how to proceed from there. ~~ I agree with taking a look at the man pages, but I think what you are looking for is creating the actual CD image - what I have managed to do, using FreeSBIE 1.1 as a base, is to create my own image and burn it to disk. the following is the incantation:- mkisofs -b boot/cdboot -no-emul-boot -c boot/cat -J -r -ldots -l -L -o my.iso directory for image Note 1: cdboot is a file in the boot directory Note 2: fstab = /dev/acd0/cd9660ro00 You can change the entry in fstab to boot whatever partition you like, as long as it is / (I am not an expert, but it worked for me - I am still experimenting.)

OK so my proliant 3000 server will not boot to the ide HD that I have successfully loaded FreeBSD 6 beta on 3 times. So what if (and most improtantly HOW) I create a CD with the / and /etc on it that would get the kernel, and the config files from /etc, then once the kernel finds the ide hd, the /usr and /home could stay on teh HD? Does this make any sense? I just want to boot the 3000 far enough for it to recognize the ide HD and then switch to it for the rest. And it does find it when it shows the drives during the boot sequence with the install CD in. Mike While there are many notes on creating your own distribution disk, it is probably easier just to figure out why you can't boot from the HDD. How about giving us both a dmesg and an fdisk report? -gayn ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
