My subject says it all, and I need your help. First, I'll be honest and say I know nothing about Linux, and since it is not required of me in my job to support Linux, my desire to learn all the ins and outs of it is really non-existent. I only want to find out how to make the subject line work, and be able to save the steps in case of program updates in the future. I also know the previous statement may not help in obtaining help here, but I did want to be upfront with everyone, so please at least review my scenario: My job is to build and test PCs, running vendor-specific diagnostics on each. These diagnostics are on CDs, and I currently have table space to build and test 24 PCs at one time. However, more and more of our PCs are being built without CDROM or DVDROM drives. This requires me to attach a CDROM drive to each of the 24 to test. After testing, the CDROM drives must be disconnected and returned to the shelf. As you can imagine, this can become quite tedious. I've approached our software support group with the idea of placing these linux-based diags on a USB thumb drive, but they said they didn't have time for a project such as that, nor did they want to have to support such a venture in the future, in case the vendor releases a newer version of diagnostics. So, I approached a friend of mine that has some knowledge of these things, and he has the thumb drive booting fine to a certain point, but then it goes out and looks for the diags on the CD. Of course, with no CD, it hangs. He has tested this approach by copying one of the files/folders from the original diagnostic CD over to a non-bootable CD, and booting from the thumb. It then finds the file/folder it's looking for on the non-bootable CD, and the diag program runs. My question is, how do we go about finding out where this "mapping script" is and changing it? In short, how do we tell the program "Don't look for the CD, look HERE on the thumb?" Thanks in advance for your patience, and any assistance.
