I am attempting to install firmware on a SunBlade 100. I need to first upgrade the PROM. I have tried a few different ways, but I cannot make a CD (with the PROM) that the machine will boot. Does anyone know how to repackage the PROMs into ISO images that the Sunblade will boot? I trashed the disk trying to copy the PROM to the disk, so using the hard disk is not an option. I suppose thats why the driver was listed as dangerous!
