Help with 2.1GB on 755cd

[Joshua Hosseinof <hosseino@ymail.yu.edu>]

I bought an IBM DCRA-22160 hard drive which is the 17mm 2.1GB IDE hard
drive that IBM sells.  I've put it into a spare caddy aand plugged it in
and I get error message 174 on my 755CD.  I've tried a different hard
drive with the same caddy and connector and it works.  Is there something
special I have to do to use the 2.1GB hard drive??  All I've had until now
in this machine was a 540MB.  I've tried with a bootable Dos disk in the
floppy drive but I still get the Error 174 and no way to get into
Easysetup.
