Kurt:

Let's see here;
1. Did you get the WDXT-GEN2 at a mail-order house as a "special"?
It does come with docs and it is P/N:  79-000446
Western Digital can be reached at (714) 863-0102
BBS Support:  (714) 756-8176

2. The "default" setting on the board will work fine for a ST225, that
is what it is designed for.

here are the default settings:

W17  out   W18  out    W19  out   W20 out  21mb  4heads  615cylinders

W21 out   W22 out   (controller 320-323)  Bios C800-C9FFF

W27  out     Selects IRQ5  

P.S.  out means jumper NOT installed.
   

W25 & W26 are always  OUT
W28 allows the controller to operate with an XT computer when
the jumper is OUT.


To low level format the drive
run debug and at the DEBUG prompt (-)  
Type: g=c800:5   <enter>
Normally Using Pre-Selected Configurations work fine for a ST225.

I hope this helps.
