I can only run the live CD on a SCSI server. All other machines complain about access to usr_cram.fs, which IS on the CD. I've tried 2 versions of puppy on a number of machines. Anybody help?
Also, is it possible to configure puppy to autostart an application on bootup. I'm interested for my touchscreen epos application. Any info most welcome.

You can add a program to /root/.xinitrc , then it is started when X starts.
Or to /etc/rc.d/rc.local0 , then it is run with the boot-sequence.

Concerning your other prob:
Depends on the computers.
This problem often happens on Windows-machines with more than one partition.

I made a patched image.gz for machines, that have C: as a ntfs-drive.
The patch forces puppy to use pup001 on c: and search usr_cram.fs there.

The image.gz also can be downloaded manually: http://dotpups.de/puppy-releases/1.0.7/installer-for-WindowsXP/

Mark, if you're there, I'm not making myself clear. I've tried to simply fire up the CD, ostensibly to use a ram only setup, but it never works except on my SCSI box. I've tried a machine without a HD and it's still the same. Don't understand!
Re xinitrc etc. I do understand such matters, but I don't know how to go about effecting this in DSL. I have made a flash drive (IDE) which works, but the OS seems inaccessible (to the naked eye). Where do I find detailled info on how to modify DSL behaviour.
Many thanks for your reply.
Tom

Hm, I have no idea what could be the reason, as I never tried to run it in RAM.
I just use Harddisk-based configurations.
So please wait, until someone else can answer.

Greets, Mark

I had that very problem with SCSI. I couldn't figure it out until I found out the method it boots up.
Because I don't like to mount usr_cram.fs off the hard disk, I used this workaround to modify image.gz and put usr_cram.fs on it:

Code:

dd if=/dev/zero of=image2 bs=80M count=1
mke2fs -F -m 0 image2
mount -o loop image2 /mnt/data

# be sure to copy all files from image.gz to /mnt/data
cp usr_cram.fs /mnt/data/root
umount /mnt/data
gzip -9 image2


Now you are ready to use the modified image. Smile
Just be sure to add an a huge ramdisk size as a kernel parameter, I myself have added the value "ramdisk_size=122880" to grub.
