cd rom

I think you have to open a channel first (to the cddrive).

Note: FAsm dereferences labels. So you'll have to tweak to compile with MASM

cd rom

Try "set cd door open wait" and "set cd door closed wait".

this code was tested on my machine (win2k) and on win95/98/ME

I tested your code (with my inc/libs) and it works...

cd rom

Sometime the problem is not software but hardware. For example when your cd-rom is connected like slave drive to the same IDE cable where is your hard disk then your source code doesnt work. You can add another IDE cable and make your cd-rom to be second master and then all be OK. I test it and I am very amazed from it.

cd rom

Connecting a {DVD, CD}-{BURNER, ROM} on the same cable as a harddisk is a BadThing(tm) because it slows down the HD.

cd rom

yea i guess that was the problem i was running into testing on other machines they had 2 cdroms etc . ijust dont have a cdrom on my laptop to test no my own so i had to rely on others i sent it to telling me it didnt work , so i just thought it was something in my code :alright:
