Half on, half off -- New CD-R drive and 512-byte blocks

I do know, from experience, that any SCSI Plextor CDROM/CD-R/CD-RW will boot
basically anything -- Sparc, SGI, RS/6000, HP,.... I've tried plextors of
varying ages (old 8plex caddy-loader up to a 12/4/32 CD-RW that's about 1 year
old) and they all work great...
