- I am trying to use int 25H (Absolute Disk Read) to access the
- BIOS parameter block of a logical hard drive. The interrupt works
- for floppy and hard drives from within a DOS program, however
- in Windows protected mode it only seems to work for floppy
- drives. My purpose for reading the BPB is to obtain the Volume
- Serial Number of the logical drive. If you know of any way to
- read the Serial Number from within a Windows program, please
- let me know. Please respond by E-Mail and I'll post a summary.
-
- Thanks. Avi
