Hello asm guru's!

I have pieced together my own spoof operating system from stuff i've read.

It only knows 3 commands but it supports basic in/out interface =)

Right now im booting from floppy drive (FAT12) on my test pc.

My other pc has no floppy drive, but can write/read cd's.

I would like to write my own strapper for cd drive booting.

I dont want to use FAT12 format but my own instead.

Does anyone have any ideas on how i could skin a cat of this breed?

Could i just write the 512 byte boot sector to the beginning of a clean cd?

Any help would be greatly appreciated.

Ok, thanks and happy coding...

about where i'm at...
'el torito' is the cd boot standard; not sure the world needs a new fs, but you get 2KB for your bootcode with cdfs

CD do not uses the same boot method than floppies or hard disks,it uses
boot descriptors and can load more than one sector,read 'el torito' specification for more info .
If your computer can boot from usb ,i recommend to forget cds and use usb instead.Or better boot from the hard disks ,there are boot managers
to allow booting many oses(windowsxp also has a boot manager).

Yes i have USB!

I prefer not to keep stuff like this on my HD.

How might one go about writing USB booter?

first look at the bios options for booting from usb to see wich kind of emulation it can do.

Im a bit lost on where to seek this information.

When i google the net, it comes up with 1685631 results...

There are just way too many pages to look at.

(Especially when your connection speed is 26.5 kbps on a good day)

Can someone throw me a link or two, or three?

Ok, thanks...

For CD booting, you just need to make a bootable floppy image, it does not matter what file sys, has long as its bootable.
Then using your CD burn software, click "make bootable" in the options, then point it to a bootable floppy image or a floppy drive, with the bootable floppy in it.
It wiil then add some bin files to the CD and now its bootable.

USB is not that easy, there no one way to boot usb, you need to try differant methods.
This may give you some pointers

to boot from cdrom:
three times:

1 get a bootable cd
2 get a computer with cdrom drive
3 boot the computer from cdrom

You can make a floppy image (made from FreeDOS diskcopy, RAREAD, etc.) into a bootable .ISO via either MTOOLS or MKBISO. And Smart BootManager can (supposedly) boot from CD-ROM even if your BIOS doesn't support it.

one theory:
http://en.wikipedia.org/wiki/ISO_9660
compile an iso 9660 image wih fasm, need a macro
file.iso
burn
boot???
