2 disc install, can't umount 1st to continue install with 2nd
There is a database app I'm installing from 2 discs. The first disc has the program and part of the data, the 2nd disc has the rest of the data. It gets to a point where it tells me to put in the 2nd disc, but it won't let me umount the drive because the app still has it open.
I tried umount /mnt/cdrom but the device is busy.
If the app shuts down at this point, it says it needs the 1st disc when I try and run the app. Not a very sofisticated piece of work.
Anyone know how I can switch the discs?
Thanks in advance.
