On systems without CD-boot facilities, trying to install by booting into DOS and running autoboot.bat doesn't work. This is because the path for initrd.img is invalid. By experiment, I discovered that the following alternative contents for this file work as required: Q> loadlin autoboot/vmlinuz initrd=autoboot/initrd.img
this is fixed in the latest Raw Hide install image...
*** Bug 5457 has been marked as a duplicate of this bug. *** There appears to be a problem with installing RH 6.0 from CD-ROM on a system where DOS is present, as the instructions to do D: then CD \DOSUTILS then AUTOBOOT fails at the final step with reports of a missing file.
