Haven't seen any problems from you for awhile, thought you were done... First, let's clarify the original configuration and the current configuration... Did you originally have only one hard disk and it was an IDE or EIDE drive ?? Are you aware that a single IDE or EIDE disk must be jumpered as a "single" drive, and if you add a second disk to the same channel it will be called a "slave" and must be jumpered as a "slave", and that the original disk that was jumpered as a "single" must be changed to "master" ?? Most modern BIOSes report how many drives they have found. If your BIOS is not reporting both, that's where you begin. Pull both drives out and re-check the jumpers. You must have at least one of them wrong. An IDE or EIDE channel supports two disks, one is called "primary" and one is called "slave". The "primary" gets jumpered as a "master" and the "slave" gets jumpered as a "slave". There is support in most modern BIOSes for two IDE or EIDE controllers, each supporting two drives. The first IDE channel normally uses Int 14 and the second channel normally uses Int 15. Some BIOSes even report these as part of their PNP support. Lots of luck and get back to us with more info if you have more problems... To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
