Floppy booting images:
boot32.img - for any 32bit SPARC, all types of installations
boot64.img - for any 64bit SPARC, CD-ROM and harddisk installations
boot-net64.img - for any 64bit SPARC, NFS, FTP or HTTP installations
Network booting images:
tftp32.img - for any 32bit SPARC, all types of installations
tftp64.img - for any 64bit SPARC, all types of installations
Due to a bug in the firmware of most UltraSPARC computers manufactured by
SMCC (UltraAX and UltraAXi should work just fine), booting from the floppy
drive does not work. Therefore, boot64.img and boot-net64.img files will
not work on most systems UltraSPARC systems. Boot from the CD-Rom or
tftp64.img if boot64.img or boot-net64.img does not work on your system.
