Why does the 1740 spoof head/cylinder numbers? I have a 670 MB Hitachi
drive tied to the Adaptec. When the hard disk setup shows you the drive
configuration, it indicates 64 heads and ~630 cylinders. This looks like
a "1024 cylinder spoof" since the Hitachi drive has more than 1024
cylinders. Unfortunately, you cannot enter the drive defect table unless
you know the spoofing algorithm.

The Adaptec bios cannot be turned off - if it is turned off, it will
not run under ISC.

Is there any way to turn off the spoofing???

Other than this VERY serious configuration problem associated with (i think)
the Adapted bios, ISC unix runs the Adaptec quite nicely....
