Yes, it is possible. You will need disc software such as a "boot-disc".
These can be obtained from several locations. I used to do homebrew on the Sega Dreamcast, and I used something called "Utopia Bootdisc". I was able to burn the .iso image perfectly, and then it booted backups, etc perfectly. Of course, that was the Dreamcast.
Sony uses a special color-coded disc, however I don't think this really matters. You just need a boot disc. Look around. See if you can find a boot-disc iso. Make sure you burn it at 4x, or even 2x if possible. Sometimes you have to "play" with the PS1 to make it read the boot-disc.
Make sure no cd's are in the console. Turn it on with a original, straight PS1 game. As soon as the white PS1 logo appears, quickly open and swap discs. If done correctly, this will force the console to bypass the region lock and read your swap(boot) disc. This is also known as the 4-Second-Trick.
Hope that was helpful!
