Having spent my last pennies on upgrading my XT to a 286 I found that
the AT hard disk controller I hsd bought didn't work. (The perils of public
auctions) I did however find that the XT controller would work if the
BIOS setup was set to drive type NONE. Since I have been told that an XT
controller cannot work in an AT machine I would like to know if any damage
could be caused by running the machine like this. The BIOS is AWARD v3.03
(I think), the controller is an unamed Taiwanese card and the drive is
an ST225.
Thanks in advance.

Your throughput might not be as bad as you think, especially given that it is a st225. You might want to re low level format the hard disk to get a better interleve factor. There are program which calculate that, spin-rite is a commercial example. In all honesty, a little larger is better than a little too small. 5:1 is better than 3:1 if it really can't read sectors as fast as 3:1 and has to wait for the disk to spin around again. bruce -- | Bruce O'Neel | internet : oneel@heasfs.gsfc.nasa.gov| | Code 664/STX | span : lheavx::oneel | | NASA/GSFC Bld 28/W281 |compuserve: 72737,1315 | | Greenbelt MD 20771 | AT&Tnet : (301)-286-4585 | Thats me in the corner, thats me in the spotlight, losin' my religion -- rem

IBM's AT design allowed for XT controllers to work like this, and you obviously have gotten it to work, so whomever told you that it "cannot work" was being rather conservative. Why do you fear _damage_? Perhaps you should only be fearing boredom from the slower-than-optimum performance. -- Steve Pacenka, Cornell U.
