Virus Infection and Booting from the CD-Drive

i'm new to mac's, i bought a used PowerPC about 1 week ago, it is infected with the
nVIR.A virus, i'm running MacOS 8. i can clean all the infected files except the SYSTEM
and the FINDER files because 'they are in use'. To clean them i'd have to boot from
either a bootable floppy or from the cd-drive.

 1) how can i make a floppy disk bootable? i found only one program which allows me
to erase a disk, but there are no options to make a floppy bootable!??

 2) how can i boot from the MacOS 8 cd-rom (or from boot able CD's in general)?
in the documentation it tells me that i have to hold down the C key after i turned on
the computer, but it doesn't work, it always boots from the hard disk drive!??

  thanks

i got rid of this sucker! :)
i made a copy of both system and finder, cleaned the copies, trashed the originals (trashing system and finder, hmmm... but.. :) and then copied the copies back over the originals. after rebooting, a last scan, and nVIR.A was dead!

but i'd still like to know why my MacOS 8 cdrom doesn't boot and how to make a bootable floppy (this would save me alot of hassel next time! :)
thanks

You can only boot from an Apple CD-ROM drive (according to lore, which is often wrong).Get yourself a Zip, Jaz, another HD, hard partition your existing HD or create a RAM disk to boot from.

Bootable Floppy available at:
ftp://ftp.info.apple.com/Apple_Support_Area/Apple_Software_Updates/US/Macintosh/System/Mac_OS_8.1_Update/ Disk_Tools_PPC.img.bin

You will need this to open the download:
ftp://ftp.info.apple.com/Apple_Support_Area/Apple_Software_Updates/US/Macintosh/Utilities/Disk_Copy/Disk_Copy_6.3.smi.bin

All Apple online software for Mac is at:
ftp://ftp.info.apple.com/Apple_Support_Area/Apple_Software_Updates/US/Macintosh/

Disinfectant 3.7 is good for most viruses, but is no longer being updated, so beware.

Have fun with your new "Toy,"

If you have an internal CD-ROM, Hold down the "C" key at startup.

the hdd.

from floppies? hrm@#$%

Locate the Control Panel called "Startup Disk" and open it. Mounted volumes may now be selected to boot from. If the volume selected turns out to be invalid, the Mac will boot, in order of appearance, from:
Chain 0, SCSI ID 0, 6, 5, 4, 3, 2, 1,
Chain 1, SCSI ID 0, 6, 5, 4, 3, 2, 1 (only some models have 2 chains).
