burning CD-Roms that are readable on my T21

[ja-rek]

Hello,

my old T21 currently has only MS DOS installed.
I am trying to burn a CD on my other notebook to use it on T21.
However, the CD is readable on that notebook but not on T21.
I tried different software (ImgBurn and Nero) and two different notebooks to burn the CD - but without success.
A friend of mine managed to do it once (he burned a CD readable on my T21) but he is not available now and might not remember details.

Question:
1) what sofware to use
2) what settings to use
to burn a CD-R that is readable on my T-21?
I don't know what is the make of CD-R/DVD-R in my T-21.
The label says only "DVD-ROM"

thanks for help!

You'll need to install cdrom.sys and mscdex.exe to read a CD/DVD drive.
See here: https://support.microsoft.com/en-us/kb/825426
After that you should be able to read any CD or DVD.
