is solaris (sparc) "bootblk" program sit inside the MBR?

As part of the solaris 10 boot up process, PROM will load "bootblk" program which in term locate and load the "ufsboot" program. I am just wondering if bootblk here is actually the boot loader sit inside the MBR and ufsboot is the one sit inside the Filesystem ?

I am guessing solaris (sparc) boot loader should work the similar way as grub? (ie. first to to MBR to run the 466byte program which in turn look up the secondary boot loader file reside in FS and then the kernel can be loaded.

Can someone helpe me clarify this concept?

None of the links above mention about MBR(master boot record). Does that mean Solaris(SPARC) doesn't format the disk with MBR?

I already know the general boot up process.
*****Whatt I want to know specifically is that if the bootblk program (called by PROM) is stored as part of MBR. Sth like this http://linux.vbird.org/linux_basic/0510osloader//mbr_boot_sector.gif [it is linux though]

ps: the last filesystem is "others". Sorry can't find the english diagram.

so we can almost regard the (vtoc + bootblk) is the equivalence to MBR for the x86 Solaris10 (which using grub)?
