First you need to boot your system to the install program. You will have to create your boot floppy, and creating it depends on which version of the PROM you have. The ``images'' directory on the CD contains two images. Use boot-v0.img if you have a PROM version 0 or 1 (this is the major number...PROM 1.6 is a type 1 PROM). Use boot-v2.img if you have a PROM version 2.0 or greater. To create the floppy, you can use rawrite.exe under DOS (in the dos-utils directory of the CD) or you can use dd under a *nix variant. Under DOS you would enter the following commands:
d: cd \images \dos-utils\rawrite
When prompted, type in the file name of the image to write to floppy.
Under a *nix variant, you would enter commands such as:
cd /mnt/cdrom/images dd of=/dev/fd0 if=boot-v2.img
Replace boot-v2.img with boot-v0.img if you have a version 0 or 1 PROM. Also note, do not use /dev/rfd0 under Solaris; it will not work. Use /dev/fd0 instead.
Insert the disk and at the PROM prompt type ``boot floppy''. You
will be presented with a SILO prompt. If you wish to do your install
using a RAMDISK (will use about 2M of RAM, recommended if you
have 8M or more of RAM), you can just press 
at the SILO prompt.
If you wish to do an NFS rooted install, you will need to supply some
paramters here. The formula of what to type is:
linux nfsroot=nfs.server.IP.address:/path/to/RH/image
For this to work you will need a rarp entry or a bootp entry on your network that will give your SPARC it's IP address. This is covered in the section below.
