Better insert

Make sure you've got initrd-tools >= 0.1.10. Then create these files
(watch out for the tabs):
--/etc/mkinitrd/exe--
/bin/mount
/bin/umount
--/etc/mkinitrd/scripts/dma (must be executable)--
#!/bin/sh
cd $INITRDDIR
mkdir proc

The boot hangs at or right after the partition check. Once in a while, bootup messages give one additional line: "INIT: version 2.78 booting" The boot looks like it always hangs during or right after the partition check of my second hard drive which is where all my linux partitions are. I guess that may mean that probing the ide drives may be causing some sort of problem. In one of your earlier messages, you mentioned turning off DMA. I've done some searching with google, looked at documentation for kernel and lilo, and I'm not quite sure how to do that. Would I need to intall hwtools and hdparm and put put add an hdparm line into /etc/init.d/whtools? Or is there a way to do this passing parameters through lilo at boot? I'll be out of town the next five days, and won't be able to do any thing else on this until next week. Thanks for the suggestions and help. -- Jerome

Uh, yeah ... it's devfs at work.

Is the disk light on at this point in time? If it is, you need to turn
DMA off on your IDE disks.
