For some reason and thanks to Dell’s incorrect info, the firmware upgrade crashed.
Can anybody tell me the process of how BIOS identifies the DVD drive ?
I am more talking about a software solution - using tools like dos debug.exe. How can I read the raw IDE port ? I can do that for IDE harddisk using debug.exe esp by booting DOS.
I am looking to bpass BIOS if I can directly read/talk to the device.
Any help will be great. I dont mind writing something in C++
