controllers (including SCSI id 7 on the 2100/3100).
- On the pmax (2100,3100) set the host SCSI id to 6.
- Move disk and tape config for the second ASC controller from the GENERIC
config file to scsi.pmax so all configurations can use the second
controller.
* dec_5100.c: sysconf, interrupt, and motherboard (drain writebuffer)
support for 5100.
* support for hardware kludge in 5100: sii DMA buffer is hardware
padded to alternate 32-bit words, not alternating 16-bit halfwords.
* 5100 has no framebuffer, console is wired to serial port 0.
With ibus support, boots as far as exec'ing init, and hangs.
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.
