Earlier this week I had asked about my Seagate 43401N drive 
which wasn't being read correctly.  I had several dozen people 
mail me telling me to fix the partition table, and I tried to 
tell as many as I could that BSD wasn't even getting as far as 
reading the partition table, and the disklabeling program 
wouldn't even let me access the disk to make any changes.  Even 
turning off extended translation in the adaptor setup didn't 
work.  After screwing around for a few days I found the 
solution:
TURN OFF THE "INITIATE WIDE NEGOTIATION" BIT IN THE ADAPTOR 
SETUP!  That worked.
Now I have another problem.  I recompiled a kernel to add a 
second adhc device for my other Adaptec 2742, and took out all 
of the superfluous device lines in the kernel configuration.  
It compiled correctly, but hung right after finishing loading 
the kernel and probing devices (but it did probe the second 
adaptor correctly).  I started over from GENERIC and this time 
the only change I made was adding the second adhc device.  Same 
problem.  I made the device line exactly identical to the first 
device line except for changing adhc1 to adhc2.  I am not 
loading the BIOS from the second adaptor and I changed the IRQ 
on the second one to 12 (the first IRQ is 11) because when they 
were both set to 11 (Adaptec says to keep them the same) BSD 
refused to probe the second bus.  Any suggestions?
