Bootable CD disk does not work in DVD drive

Hello,
Many years ago I created a bootable CD which pretends to be A:\
drive at the bootup (it boots to A:\ prompt).
It was working great for all these years.
Now, I have a new computer with DVD drive (DVD +/-RW / CD-R/W) in it and my
CD is completely ignored at bootup.
I wonder what can be the reason. Other CD bootable disks (vide Windows
installation disk) work OK.

Give this a try:

To make a CD auto run, make a file in the root called
Autorun.inf To make one, open notepad and enter these
lines replace setup.exe with the file you wish to autorun):

[autorun]
Open=Setup.exe


Save it as autorun, notepad will add the extension .txt,
just rename the file to Autorun.INF and drop it into the
root when burning the CD. To see examples of this file,
just grab any CD that you know autorun's, and explore the
root, find the autorun.inf file and open it with notepad
to view the contents.

A bootable CD is different to an AutoRun CD. The OP is looking for a
bootable CD fix for the DVD boot failure
 
That is valid for the Windows environment I suppose.
I am talking about initial stage of booting computer.

Don't know, but the 'many years ago' part could possibly be a problem.
Try a new burn if you still have the creation software else extract
current cd to .iso then reburn. Can't do any harm.

If it completely ignores it then the boot sequence is set so that the
optical drive is not scanned prior to the hard drive(s). Even with
the sequence set correctly it's doubtful the CD-ROM will boot.
It probably uses drivers that are IDE based and the new PC will
likely have SATA so the CD-ROM won't completely boot and
fail on detecting the DOS level optical driver. There is a driver to
load SATA at a DOS level but requires a lot of work and use of
command qualifiers to get it to work.
 
Thank you.
Your explanation makes sense to me.
What about if I burn the same bootable image on the new disk using that
drive?
Will that solve that problem?
Should I use CD ROM or DVD disk?
Thanks,
Jack
 
The image would still contain DOS mode drivers specifically written
for a IDE controller ( Parallel ATA ). Those drivers won't work on
a machine where the Optical drive is SATA based. ( I'm assuming
your Optical is SATA, not PATA ).

Disk type isn't important, either would work but using a DVD-R is
wasteful since the original CD was large enough.

I've built a Real Mode SATA based optical disk, but the drivers are
very chipset specific. My bootable disk is built for an Intel ICH8 for
a 965 based chipset. The driver name is GCDRom.Sys. You'll find
the driver on the web, but configuring it is anything but easy.
 
Thanks a lot.
That will be the new challenge for me. As more difficult it looks then I
feel more motivated to do it.

The only thing I do not understand is that the DVD drive is IDE drive.
Fact, my hard drive is SATA but booting from removable media should not
involve the harddrive regardless the type it is.
