NanoBSD :: smallest image size

[Paul Procacci]

Hello list,

I have an old machine I just acquired that I was thinking of replacing 
my current FreeBSD firewall/router with.  It's a Celeron 500+ Mhz 
machine with 32 Megs of ram, and a 10G hard drive.  I am(was) initially 
thinking about taking out the 10G, and using the flobby disk drive to 
boot off of.  I was familiar with PicoBSD years ago and know I could use 
that, but it seems that project has been discontinued.  After looking 
through archives to determine what to do, I can across nanoBSD as that 
seems to be included in the FreeBSD system by default, henceforth this 
question.  I couldn't find any information regarding the smallest image 
size possible using NanoBSD.  So the question is: can nanoBSD fw/ the 
proper configurations fit onto a floppy disk...and if not, is such an 
old computer bootable off of a usb stick?  How can I tell without buying 
one?

Thanks,
~Paul
