Sorry, but it is not really the right answer, I think.
I need to make an bootable CD-ROM and when I have to use it, I want to follow the following steps :
- boot from CD-ROM
- from this CD run an special
executable
- after that we stop the system

hi labrune

If you start from install and core, you can select "run a recovery shell" so you have a minimal OS.
Is sufficent for you?

Hello,

You can use the "Expert Recovery" method using the core media. To read through the steps required read the following documentation:

HI,
I think we are on the right way!!! Now the problem is How i can create my own recovery CD and include my executable. In that manner, if I boot the CD, I can load (with lhe "l" menu) my executable and run it.

Try a decent cdrw utility that can manipulate ISO images. Copy the cd to hard drive, add your executable to the cd image, make sure the total size of the iso image is not larger than the capacity of a burnable cd and burn to cd. I've used Gear Pro for Unix and it seems to work fine. I created custom bootable recovery cds for Solaris systems which required a slightly more complicated procedure. I haven't done this for HP systems but I don't *think* HP cds require special boot blocks for different machine types or custom VTOCS so it should be easier.

Hello,

The answer to that is make_medialif. make_medialif creates a bootable LIF image. This image can be copied to either a DDS tape or a writable CD to create an Ignite-UX install media normally, but in your case you could use it to include your executable. You will need to install the ignite software to access it.

To create a boot LIF image using the config file
/home/root/myconfig and placing it in
/home/root/uxinstlf.

make_medialif -f /home/root/myconfig -l /home/root/uxinstlf

Then using a CD writing utility, transfer
/home/root/uxinstlf to a writable CD in raw mode. The resulting CD will be bootable.
The image can be transferred to a raw disk and a system booted from that disk to test out the image before committing it to CD.

See the man page for more details.

Please don't forget to assign points to all of the respondents who took time out to help you with this issue.
