I wasn't able to access this URL even after changing the hostname to
hpdmlad.boi.hp.com.

However, Steve Messinger and Larry Copp of HP were kind enough to
reply by e-mail and tell me what the jumpers did.  In addition, Larry
correctly identified the problem as the SDTR jumper, pin pair 3
counting from the LED on the drive front, which is on when the drive
is in a 700 series machine but should be removed for almost all
others.

This gets rid of almost all problems.  I'm now trying to install Linux
on part of this drive, and creating the swap space with mkswap on the
swap partition fails with a SCSI timeout, but _only_ if the swap
partition is on the last few (highest numbered) cylinders of the
drive.  If I move the swap to right after the DOS partition (cylinders
700 to 720, roughly), mkswap works OK.  This has me eyeing the 'sync
spindle' jumpers.  I also note that Linux reports the drive as having
1001 cylinders, but the hpC2447_noswap disktab entry says it has 2075.
