There is actually something wrong with that 98 boot disk image, along with the disk 2 of pc compatibility. neither of them will load for me. I created a 98se bootdisk however with CD ROM drivers, and included the APPLEVDO.INF and its accompanying read-me file. It seems that you can download and use the newer version of pc setup further down the page (it says it has issue with OS9 but you are using 7 so that shouldnt matter.
