Hi, i am trying the whole day to make a bootable CD. I have read a lot of postings in newsgroups, but there remain a few point unclear. first suse and redhat (sorry but if you use search engines on the web refering initrd, ramdisk and so on .. you just get answers about SuSE and Red Hat Distributions), they use both initrd. My question is , is it not possible to use a boot CD without initrd. The reason is i have made a rootdisk about 25 MB in size for my needs which exactly serves my needs. This is a normal rootsystem as you would use it on a harddisk. So the idea is just to put these system on the CD. I have read the Bootdisk Howto and CD Writing Howto, but there is no where explained what the root system contains or is made of. Further if i take a bootdisk as boot image what root device must be used in the kernel. I managed that the system boots from CD but never mounts the root system. What is the rootsystem on a bootable CD. Floppy /dev/fd0 or /dev/hdb when u use your CD as slave on the first controler. I cant find any answer on the web regarding this questions. I have ruined quite a amount of CDRoms. By the way I tried it with xcdroast, syslinux (isolinux) it didn't work. So the explanation how i did it. first i put all the root stuff under /rootdisk . afterwards i made /rootdisk/boot where i put the diskimage from my floppy called boot.image. then executed command mkisofs -r -b boot/boot.image -c boot.catalog -o bootcd.iso . and then cdrecord -v speed=6 dev=0,0,0 bootcd.iso I tried syslinux isolinux too where i got error cant find root device 03:40. So if anyone has an answer to my questions or can point me to resources where i can find it on my own that would be very appreciated. kind regards Manfred
