I have a Power Mac 6100/66 with Plextor SCSI CD burner. I am running system 8.1. My burning software (toast) requires sys 9. So, when i tryed to upgrade from 8.1 istaller wont run. It needs to be booted from CD, but I can not. I use Toast ReadCD extension to acces my CD Drive. With standard Apple CD it does not work. Can anyone help? (How to boot from CD, or how to install sys 9.1, or how to burn under 8.1...) Thanx marek

Toast 4 will run fine under 8.1. See if you can find someone with a copy, since I'm guessing you probably have Toast 5. I take it you don't have an internal CD-ROM drive in that Mac... If holding down cmd-opt-shift-delete with a bootable CD in the drive doesn't work, there's no way you'll ever be able to boot from that drive. The good news is that internal CD-ROM drives that *are* bootable cost about $20 for a drive and bezel for the 6100-series Macs, including shipping. Check out eBay or the Low End Mac Swap list: http://lowendmac.net/lists/ p

Thank you, but Toast 4 is not a solution for me :-( I can not buy it... And also, buying an internal drive will be a bit difficult, because I live in Europe... But, when I asked for help in local apple dealer, they promissed, that, they will prepare for me a set of disks, which will solve my problem (bootdisk with driver for my CD Burner). Thank you, for you interrest. Marek BTW Holding cmd-opt-shift-del disables extensions only (like holding shift)

Holding cmd-opt-shift-delete will boot from, in reverse numerical order, starting with the highest number, any other SCSI device on the bus *other* than the startup disk. Some CD-ROM drives that won't boot when you hold the C key down will boot when you use cmd-opt-shift-del to boot them. Apparently yours won't. :( p
