I am sorry for the late of this response.

Thanks, Frank... the patch was the solution for my problem
and the server Dell 4400 is working now.

NetBSD 1.5.2 is installed now in sd0 and sd1 under ahc1
(aic7899) and works very very very fine.

The enumeration of the pci buses is wrong yet, but it seems
like is not a problem. If you wish to do more testing with
this server, please tell me... This server will be out of
production for two weeks.

At the end of this message is the "dmesg listing" of Dell 4400

Thanks again, Frank.
