madmax is correct. You can't backup a boot disc - only original games or games that have already been backed up (from one CD-R to another blank CD-R).
Judging from your first post, I thought that you wanted to find out if your CD burner supported burning PS1 games.
All CD burners support the burning of PS1 games - but not a single CD burner can burn the PlayStation boot sectors hence the reason why we need to find a method of bypassing the boot sectors so that we can boot up the backup discs. As far as I know though, it is not possible to make a successful backup of a boot disc. And by successful I mean finding a method of booting up the backup of the boot disc without the need to "mod" your system.
The boot disc method often involves having an original disc in the first place or a disc that acts like an original game so that you can fool the system into thinking that you've got an original game in the drive.
So instead of loading an original game (like you've just fooled the system into thinking), you're loading program code instead which in turn allows you to boot up those backups that don't have the boot sectors located anywhere on the disc.
I hope that this clears things up.
