As mentioned by dmccunney on the FreeDOS user mailing list the other day, if you've not already seen it there is another good interesting Virtual x86 emulator @ http://copy.sh/v24/ This emulator supports graphics unlike JSLinux doesn't need Java (e.g. unlike JPC). V86 (V24) currently has 4 different hosted images you can boot (KolibriOS, Linux 2.6, FreeDOS, OpenBSD), you can download images after you've played around with them. FreeDOS boots very quickly and has a number of applications. You can also boot your own CD, Floppy or hard drive images! Cutting and pasting is a simple right click, e.g.
SeaBIOS (version rel-1.7.3-74-g3061815-dirty-20131005_235927-eevee)
Booting from Floppy...

Kyriakos Ktorides provides a good quick overview on of V24 on his website Kyriakos's Den: x86 Emulator in your Browser. The osdev.org forum discussion may also be of interest.

WATCHOUT: If you use reset or buttons be aware that until you click into the text console again that they will still be highlighted, e.g. if you last hit reset then unless you click into the console when you start typing it will reboot again as reset will still be highlighted :) Still testing....

For anyone new to the BTTR forum, you may find the past JSLinux / Runcom discussion also interesting.

On a semi-related note Rod Pemberton's list of BIOS calls used by various OSes, bootloaders, etc., online references was an interesting reminder for me of some references I've referred to myself in the past. I'm mentioning it as I thought it was a good starting point for anyone interested in low level who may not be aware of some of the references he refers to.
