I'm having some trouble with something I want to do to my OS. Here's what I want to accomplish:

-I first want a system where I can prompt the user for a sector number, they can type it in, and then type in a program/text file/etc.
-As a few subfeatures to this system, I'd like to implement a way for users to recall and view/load and run the sectors.

Also, would it be easier to skip this whole raw sector business and impliment FAT12 reading/[later on] writing? The OS is in realmode btw. If anyone has any information or tutorials on how I can implement FAT12 (or the weird sector-system I explained before...), I'd appreciate it. I've googled and come up blank =/

Thanks in advance for any help,
Anthony

for floppy operations you can use int $13 or http://www.dex4u.com/images/FloppyDriver.zip (dex4u's floppy driver[works in pmode too])

int $16 can be used to read key input and int $10 can be used for printing (for the console interface)

for a basic prompt you could do something like


from there you can parse the command line for the sector number and convert it to a number then read that sector or what have you

Thanks
I'd still like to know how to implement FAT12 though, for the future.
Does anyone know any tutorials or examples on how to do this easily? I hear FAT12 writing drivers can be a nightmare =/
