It is supported in 2.2.8, but not the 3.* stream. Nor current. I'm told
it's because of the way in which the PCI bus is now initialised.
This should tell you everything:
FreeBSD 2.2.8-RELEASE #0: Mon Nov 30 06:34:08 GMT 1998
jkh@time.cdrom.com:/usr/src/sys/compile/GENERIC
CPU: i486DX (486-class CPU)
real memory = 33554432 (32768K bytes)
avail memory = 30334976 (29624K bytes)
Probing for devices on PCI bus 0:
chip0 <Intel 82424ZX (Saturn) cache DRAM controller> rev 2 on pci0:0:0
ncr0 <ncr 53c810 fast10 scsi> rev 1 int a irq 11 on pci0:1:0
ncr0 waiting for scsi devices to settle
(ncr0:0:0): "DEC RZ25M (C) DEC 0680" type 0 fixed SCSI 2
And here's the diff which allows the above to be seen during the 3.* install:
RCS file: /usr/cvs/src/sys/i386/isa/pcibus.c,v
retrieving revision 1.41
diff -C2 -r1.41 pcibus.c
*** pcibus.c 1997/12/20 09:04:25 1.41
--- pcibus.c 1999/06/07 11:58:58

*** 260,265 ****
}
! cfgmech = 0;
! devmax = 0;
return (cfgmech);
}
--- 260,265 ----
}
! cfgmech = 2;
! devmax = 16;
return (cfgmech);
}
As for your other points, It's good to have the other points you made confirmed. Hopefully I'll be able to
try something this weekend.
Doug: you answer so many questions. On behalf of the others: thanks.
