My 7.2k 9G IBM drive might support it too. It's on mode page 0, somewhere :) Someone needs to grab the software interface so we can add the variable names to mode_pages. That or a secret-ring-decoder for the bytes returned by 'camcontrol modepage -m 0'. My UltraStor 9ES 4Gig UltraWide (DDRS-34560W)[1] doesn't appear to support it, according to the IBM specs. A link to the feature's technote (Drive-TIP) shows up for the 18XL (10krpm, 9 & 18GB sizes). They even show the chip location on the back side of the hard disk controller board.

We really need to figure out how to read the BIOS hardware moitor port on ATX MB's. IT'd be a great thing to stick on the MtraixOrbital LCD displays :) Doug White Internet: dwhite@resnet.uoregon.edu | FreeBSD: The Power to Serve http://gladstone.uoregon.edu/~dwhite | www.freebsd.org [1] Kudos to Toshiba for replacing the Crapopolis with such a nice drive. :) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
