[I am sending this again, it didn't seem to make it to the list the 1st time]
I installed NetBSD 1.5.2/i386 on an older system with an Adaptec 152x SCSI
controller this weekend. The two devices on the SCSI controller are:
1) DAT drive
2) cdrom drive
The 152x is was jumpered at IO=0x140 IRQ=10. I determined from the web site
the GENERIC install kernel on the CD/floppy has the IO/IRQ for the 152x hard
coded as 0x330/11 (or something like that). Since this was the case I found
that I had to crack the case and reconfigure the hardware in order to install
NetBSD. I know that FreeBSD provides the user the ability to configure IO/IRQ
for devices prior to booting the kernel, is this possible with NetBSD? It is
a real pain in the ass to have to reconfigure hardware in order to install the
OS...
Which brings me to my second question...
I figured I would build a new kernel on my other NetBSD box with the correct
IO/IRQ settings so I could install on the old box... However I was unable to
mount the boot floppies provided on the NetBSD 1.5.2 CD. It could not be done
with either the "real" floppy device or trying to configure the boot?.fs files
using the 'vnconfig' command. I figure this is because the floppies have a
2.88M floppy image on them.
So is there documentation or tutorials on how to build custom installation
floppy?
I ask because I need to build a set of rescue floppies for this system.
Thanks,
Wayne
