You don't need any modifications to install an ST-225 in an AT.
The drive type should be type 2 (615 cyl. 4 hd.) in most cases
unless you have a really uncommon AT mother board.

The DTC controllers usually don't have build-in formatter, so
you have to use software (such as the Disk Manager) to perform
low-level format (some BIOS on the AT mother board has hard
disk formatter, such as the DTK-1230C etc.).

We have installed ST-225s with DTC controllers (both 2:1 and 
1:1 versions, a little odd? But we have to use what we have got.)
in different kind of ATs.  We have not detected any incompatibility
problem so far.

You  might need to check if the drive selection jumper on the
drive is set right.  New ST-225 may be defective, especially
when you buy in large quantity.  We usually buy ST-225 in large
quantity,  and have bad ones from time to time.
