I wanted to install YDL 2.2 on my iMac 266Mhz machine with out having to reinstall my MacOS 8.6 from scratch. I did this with the help of 2 additional software packages, Norton Utilities and FWD Hard Disk Toolkit, Personal Edition. These two utilities allowed me to defragment and resize the main partition on my the hard drive, respectively. This prepared the drive for the YDL 2.2 installation with out destroying the MacOS data currently stored on it.
A) I first installed both Norton Utilities 6.0 and FWB Hard Drive Toolkit PE 4.5 on your iMac. However, because my MacOS System folder resided on the the iMac's single drive, both utilities had to be used by booting the MacOS from their respective CDs.
B) Because my iMac's hard drive was badly defragmented I needed to use Norton Utilities' Speed Disk to optimize the drive. Again, because the MacOS System folder resides on the the iMac's single drive, I had to boot the MacOS from the Noton Utilities CD. This required that I inserted the CD in the CDROM Drive and then start my iMac while holding the C key down. Once MacOS has booted I was able to run Norton Utilities from its CD. Off of the Options menu I selected Optimize for Disk Resizing. Then I ran Speed Disk utility to optimize my hard drive. This took a few minutes to perform.
C) Once my hard drive had been optimize it was possible to resize the partition that represents the Macintosh hard drive in the MacOS. Again, because the MacOS System folder resides on the the iMac's single drive, I had to boot the MacOS from the FWB Hard Disk Toolkit PE CD. This required that I inserted the CD in the CDROM Drive and then start my iMac while holding the C key down. Once MacOS has booted I was able to run the Hard Disk Toolkit from its CD. I had to select the Device View on the main dialog and the double click on the IDE:0 master Hard Disk entry listed in the window. This displayed the Partition List dialog for my hard drive. I selected the Macintosh Hd partition entry in the dialog. Thi allowed my to select the Resize Volume button at the bottom of the dialog. This displayed the resize volume dialog which allowed my to shrink the size of my hard drive from 6 Gb down to 3 Gb. After optimizing my drive my MacOS only required about 800 Mb of disk space. This free up 3 Gb of free space for my YDL Installation.
After resizing my hard drive I was able to perform the graphical YDL 2.2 installation without much difficulty using the free space created by the Hard Disk Toolkit.
