No. It's the offset in memory of the number of hard drives in the BIOS. The BIOS has a data segment at 0x40, and at 0x40:0x75 (whose physical address is 0x475) it has a byte which is a count of the number of hard drives installed. -- John Baldwin <[EMAIL PROTECTED]> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
