Hello does anyone have a boot loader or any good resource on how to write a bootloader for Sun's Spark architecture?

Thank you

Yo,

You'll need to both obtain and provide more information about the chipset in question. Just knowing what kind of CPU is socketed into the board won't give even half enough information to know how it boots. Interestingly, if you had a clear target and purpose, you'd have known that to start off with; you can't write a bootloader for a cpu...

Actually, the SPARC specification describes part of the architecture too, and most SPARC machines boot OpenFirmware so a bootloader is more of half-stage kernel than anything else.
