Double checking grub-install -- revisited ??

Hi; I have started this thread again as a new thread. The previous "Double checking grub-install ??" lead off in all kinds of plausible directions. I think I now have more of a focus. To recap: I am getting a double Fedora grub splashimage at boot. I have a dual boot system with WindowsXP on sda and Fedora 9 on sdb. I have some experience with installing grub but made a typo type mistake during a grub install a month ago and I think (??) that might have been the root of my double splashimage problem. To check the mbr, I ran on /dev/sda: ~]# dd bs=512 count=1 if=/dev/sda | od -Ax -tx1z -v it returned: ... 000160 7c be 85 7d e8 40 00 eb 0e be 8a 7d e8 38 00 eb 000170 06 be 94 7d e8 30 00 be 99 7d e8 2a 00 eb fe 47 000180 52 55 42 20 00 47 65 6f 6d 00 48 61 72 64 20 44 >RUB .Geom.Hard D< 000190 69 73 6b 00 52 65 61 64 00 20 45 72 72 6f 72 00 >isk.Read.

[Notice the GRUB string on the second and third line and Error on the fourth line] Then, I ran on /dev/sdb: ]# dd bs=512 count=1 if=/dev/sdb | od -Ax -tx1z -v it returned: ... 000160 7c be 85 7d e8 40 00 eb 0e be 8a 7d e8 38 00 eb 000170 06 be 94 7d e8 30 00 be 99 7d e8 2a 00 eb fe 47 000180 52 55 42 20 00 47 65 6f 6d 00 48 61 72 64 20 44 >RUB .Geom.Hard D< 000190 69 73 6b 00 52 65 61 64 00 20 45 72 72 6f 72 00 >isk.Read.

[Notice the GRUB string on the second and third line as well, and Error on the fourth line] Could this double grub be the source of my problem ? If it is, how do I remove it (from sdb -- I presume)? Others have suggested that the double splashimage is just a video mode switch but then how do I account for the grub appearing on both mbr's -- Regards Bill; Fedora 9, Gnome 2.22.2 Evo.2.22.2, Emacs 22.2.1
