. Before you start you might need to consider your disk configuration to sort out a quirk in SCSI-ID to SD-UNIT mapping that exists on Sun Sparcstations.
p Upon leaving the factory, SunOS and the OpenBOOT ROM map according to this table: l -column -offset indent SCSI-ID SunOS SD-Unit t Tn Em SCSI-ID Ta Tn Em SunOS SD-Unit t \~\~\~0 Ta \~\~\~sd3 t \~\~\~1 Ta \~\~\~sd1 t \~\~\~2 Ta \~\~\~sd2 t \~\~\~3 Ta \~\~\~sd0 t \~\~\~4 Ta \~\~\~sd4 t \~\~\~5 Ta \~\~\~sd5 t \~\~\~6 Ta \~\~\~sd6 .El
p Unlike SunOS and the OpenBOOT ROM, a generic NetBSD kernel numbers scsi drives sequentially as it finds them. The drive with the lowest scsi-id will be called sd0, the next one sd1, etc.
p A truly generic NetBSD kernel is also provided as `/netbsd.GENERIC', which will do the standard NetBSD probe ordering. If your configuration differs from the default Sun setup, you can try to use this kernel to complete the installation.
p .(Note This is also a concern when you start building your own customised kernels. .Note)
p You cannot use the security modes of the sparc OpenBOOT ROM. .Dl ok Ic setenv security-mode none
p If you're installing .Nx*M for the first time it's a good idea to look at the partition sizes of disk you intend installing NetBSD on.
p Asumming a classic partition scheme with root (`/') and /usr filesystems, a comfortable size for the NetBSD root filesystem partition is about 20 MB; a good initial size for the swap partition is twice the amount of physical memory in your machine (though, unlike SunOS 4.x, there are no restrictions on the size of the swap partition that would render part of your memory unusable). A full binary installation including X11R6 takes about 150 MB in `/usr'.
