identifying controller type of given hard drive (scsi or ide)

maros · 08-24-2001, 08:10 AM

I'm trying to code a small tool in C for identifying the type of controller associated with a given drive in DOS. Specifically I'm trying to automate generation of a LOADLIN command line and I need the program to be able to identify whether the root will be (for example) a /dev/hda device (IDE) or a /dev/sda device (SCSI). Presumably this answer can be derived from something stored in memory. I just need to know where to find it and how the info is formatted. Thanks in advance for any help you can provide.

I would guess that the kernel source code will have the answer to your question. Try greping out patterns that you see in the dmesg output when your drives initalize and take a look at the source that writes the messages.
