Has anyone been able to write an elilo.conf that allows for an interactive network installation? For example in pxelinux.cfg/default I can do:
---
label vgainteractiverh72
kernel vmlinuz.rh72
append vga=extended root=/dev/ram0 initrd=initrd.img.rh72 console=tty0
---

I tried in elilo.conf:
---
prompt
timeoutP
default=localdisk
verbose=5

image=vmlinuz.rh72-ia64
label=vgainteractiveia64
read-only
append = "vga=extended console=tty0"
---

And them type in vgainteractiveia64 when prompted, but the kernel panics because I didn't append a root option. I've tried root=/dev/ram0 and that doesn't work either.

Thanks,

initrd=ramdisk.img

This is what I use to boot RH's installation kernel and initrd with elilo and tftp.

Your problem has nothing to do with the fact that binaries are coming from the network.

The kernel needs two things to boot from a filesystem. First it needs to have the device driver to access the disk controller. Second it needs to know which partition the root filesystem is in. The problem you're seing comes from the fact that your kernel does not have the valid device driver, most likely the SCSI controller, builtin. This is common with kernels from distributions. The device driver is dynamically loaded in the kernel via a kernel module which is stored into the initial ramdisk. So your problem is that you did not indicate a initrd= option in your elilo.conf. Something like this will do:

image=vmlinuz.rh72-ia64
label=vgainteractiveia64
initrd=initrd.rh72
append = "vga=extended console=tty0"

Works, if you use the vmlinuz from CD/kernels and the ramdisk.img from CD/images with RH7.1. I have not receive my 7.2 CDs yet so I have not tested.
