Xebec/IBM Debug Address for Low-Level Format??

[Marvin Johnston]

I posted the Xebec debug commands to low-level the HD sometime in the
last couple of months. Check the archives and they are most likely
there. It is not a simple "go to" like the WD controllers, but rather a
series of IIRC I/O commands issued to the controller.

> I want to perform a low-level format on my Seagate ST-225 MFM hard drive - it has the Xebec (IBM) 1210 controller card. I cannot for the life of me remember the address to use in Debug. I know how to use Debug; I've done 100's of LL formats - just not in the last dozen years or so. Does Anybody remember?? Please email off-list. Thank you.... My HDD is working, I just want to set it up right from scratch. (In case anybody's wondering, I do a LL format on IDE drives before using them, too.) Bill Pileggi
