I mean burn the bootcd as a No emulation mode, like W2K/NT4 most linux, and of course WXP. (it does not give the boot a virtual drive like A:)

I don't need a burning software :)

Hi,

Good question.

If I remember right, the ones I've made all show as a:. The CD drive letter, of course, is setable with the /L:R in MSCDEX.

I can't think how it would boot and not assign a drive letter. DOS assigns A to the first removable; C to the first fixed.

BTW, my boot CDs are 98se.

Well, if you check and linux dis. or windows built on NT tech, then the cd's bootes without any drive assigns. This is called No emulation mode.

Dear zintazu,

Maybe if you could explain why it's a problem
when the Bootable CD emulates drive A: there
would be people able to help with that? What
i recall of SoftWare which creates Bootable
CDs is that some have options like 2M88 A: or
Hard-Disk emulation but i never tried these
features and it still would be emulation...

Why it's a problem.

It's because, I use a pc testing program and it will not work, when booted from a cd that uses hdd emu. and floppy emu.

I just crashes, but when I run it from a floppy there are no problems. As far as I can see, the programs crashes when it loads it drivers libary. Think it's because it see 2 floppy drives A: (from the cd) and B: the real floppy drive, and that it can't find out the emulated A: drive.

Have you considered using 1.68mb floppy disks, the DOS version of WinImage can format these disks:

Apologies, I meant run the software from High Capacity floppies, maybe two drives?

Though if you are looking for capacity why not use Compact Flash Media, Addonics sell an IDE drive which is bootable under DOS:

Compact Flash media is available in sizes up to 512mb:

I'm thinking the real issue here is (and I've hit it too) when the emulated A: floppy boots and loads the CDROM driver then you got no more A: drive and prolly no CDROM access either. The boot hangs at that point and even though there is jo.sys and modified io.sys files out there that claim to be the fix for the problem, each time I attempt some wizbang boot CD idea of mine, I can't get there from here for this very same issue time and again.

If it were possible to load the CDROM driver from a batch file instead of config.sys I'm thinking the problem would be solved, so can we do that somehow?

freedos uses an mscdex replacement and driver that can load from the command line, no need for config.sys loading anymore.
