This is slightly off topic, but since I not a mac person at all (got a 7200/90 from someone), I am not sure if I did something wrong or not. This is probably a stupid question, but shouldn't there be a CD-ROM icon on the desktop when I am in MacOS? I am not very familiar with Mac at all.
Only if a CD is present (in the reader) *and* mounted. Otherwise, no icon on the desktop. Please note that (if the OS is ok) the CD icon appears after some time (3 seconds or more: spinup, file system identification/checks, mount).
AFAIR MacOS 7.5 has a specific system extension to enable it to read iso9660 CD-ROMs. If that is not present, you won't be able to get the icon on your desktop. Look in the Extensions folder of your System Folder for a file with 9660 in its name. If it's not there, you might be able to install it with the "add stuff" option from your System 7.5 install CD-ROM...
Right, but you also need 'Apple CD ROM' and 'Foreign File Access' (or something similar). Anyway, I'm (almost) sure that the 6.4 CDs are hybrid (Mac/ISO; info on CD#1 gives "Mac OS Standard Volume"), so you should only need 'Apple CD ROM'.
When I think about what I just wrote, I am not sure about it. I can remember I had the same phenonemon on my 7200/90, and could get the CD-ROM seen after I booted with the system extensions disable (holding the shift key down while booting!).
This can happen if there is a CD in the reader *at startup* (the system loads the driver from the CD, if it finds one). Otherwise, with extensions off you should not see anything (you may use a third party software to mount the CD later, but that's another story).
I had installed PPC 6.4, but recently got 7.3. I just wanted to reinstall using 7.3, but the CD-ROM icon does not show up. I have tried CD1 and CD2, and the CDs from the 6.4 distro, but I do not see the icon. I want to open it so that I can invoke bootx to do the install. The CD-ROM getting found, since I can see it in the "Silverlining" program that shows the SCSI devices. I had even bought another CD-ROM thinking my CD-ROM was bad...but same results.
If the Silverlining tool shows the drive, I'd think that the SCSI ids are set up correctly.
Am I totally missing something here? I had added some hard drives, but removed them thinking that may have caused it, but no. Does the CD-ROM have to be a specific SCSI ID? I wouldn't think so, but you never know.
Apple's SCSI CD ROMs always have id==3 (unless someone has changed it...). And no, the computer does not need a specific id for the CD.

As a last resort, you can grab a (free) 7.5.3 full install from http://download.info.apple.com/Apple_Support_Area/Apple_Software_Updates/YOU... Or try with a more recent MacOS... (i.e. 8.6) regards nicola
