Kickstart Gurus, I have a fully contained ISO image of the original RHEL5.1 32-bit source tree, along with some additional RPMs & a custom ks.cfg file. The goal is to totally automate the build to a VMware VM via mapping the ISO file to a virtual CDROM. I have modified the default isolinux/isolinux.cfg file as follows: default xander prompt 1 timeout 600 display boot.msg F1 boot.msg F2 options.msg F3 general.msg F4 param.msg F5 rescue.msg label xander kernel vmlinuz append initrd=initrd.img ramdisk_size=8192 ks=cdrom:/ks.cfg label text kernel vmlinuz append initrd=initrd.img text label ks kernel vmlinuz append ks initrd=initrd.img label local localboot 1 label memtest86 kernel memtest append - In my kickstart file, I of cource specify "cdrom". The ISO image will boot the VM into RedHat's initial screen, but when hit return or let it time out it, it complains that it cannot find the install media on any cdrom. I also tried to put the kickstart file into the initrd.img by uncompressing image, copying ks.cfg into it, modifying isolinux.cfg to: append initrd=initrd.img ramdisk_size=8192 ks=file:/ks.cfg Then recompressed it, moved it into proper place & re-generated ISO image. Again, the ISO will boot the VM to initial RH screen, but soon there after get the "cd not found" error. Is this just a VMware thing? My coworker has no trouble with SuSE builds working....am I overlooking something simple? Thanks in advance. Gene
