Top Document: comp.os.msdos.programmer FAQ part 3/5 Previous Document: Next Document: See reader questions & answers on this topic! - Help others by sharing your knowledge If the disk was formatted by DOS 4.0 or later, use INT 21: AX=6900 gets the serial number; AX=6901 sets it. (The disk serial number doesn't exist if the disk was formatted with an earlier version of DOS, or with some third-party formatters.) See Ralf Brown's interrupt list (<Q:02.03> [What and where is Ralf Brown's interrupt list?]), or PC Magazine July 1992 (xi:13) page 496, for details. INT 21 AH=69 also gets and sets the volume label in the boot record, which is not necessarily the same as "the" volume label displayed by the DIR, VOL, and LABEL commands. For that volume label, see <Q:05.12> [How can I read, create, change, or delete the volume label?] User Contributions:Top Document: comp.os.msdos.programmer FAQ part 3/5 Previous Document: Next Document: Part1 - Part2 - Part3 - Part4 - Part5 - Single Page [ Usenet FAQs | Web FAQs | Documents | RFC Index ] Send corrections/additions to the FAQ Maintainer: jeffrey@carlyle.org (Jeffrey Carlyle)
