I am confused... What is the reason that you don't wish to use the means
of the MBR? The hardware resets to zero, this forces the drive seek,
the first sector is read and action is taken from there. To my
knowledge, there are several other ways to perform this bootstrapping,
but this is the most flexible. Otherwise the firmware must know in
advance the record to look for, and if any means other than a specific
track and sector, the firmware would have to know how to read and
interpret the disk structure, which would make the firmware useful to
only one OS, and more specifically to only one disk format. This would
then prevent booting from anything except one disk form, unless the
firmware included a large number of formats, such as one for USB Flash,
one for CD Roms, one for DVD roms, one for Floppies, one for tape....
well, you get the point... eventually the firmware would need upgrading
quite often, every time a new device or format became available. As
much as people hate software updates, just think if they had to "flash"
the bios more frequently?
It is not that I am hellbent on not using the MBR, quite the opposite,
it is my desired way of booting for the bazillion reason you listed.
It is just that GRUB is extremely flakey when installed on the MBR on
my RAID array. I wouldn't have even posted twice about this problem if
GRUB would a) work and b) just do its job. But it doesn't and that one
hardware that really isn't exotic by any means.
I got a full F7 install on the second primary partition on the SATA
RAID1 array. I want to boot this one. GRUB doesn't do it, so I need to
find something else or ditch Linux entirely and hope that some clever
developers puts a fix into GRUB or any other boot loader.
What BIOS really should do is allow for a device driver and boot
loader to be added including some basic UI to make changes to it. In
that case, it doesn't matter which drive or format is used and it may
even make the MBR and file tables to be in a smart spot (the middle
of the drive) than on the most volatile place of a disc. Geez, even
the Commodore 1541 did a better job at that.
Yes, one would need to adjust it for any hardware or partition
changes, but at least one could get to it. Not as it is right now. The
MBR approach is ingherently flawed, but for many good and bad reasons
we are stuck with it.
OK, before we drift off into fundamental discussions and have even
more people hijack this thread, is there anyone out there who can give
an answer to my question and not tell me which issues they have and
that I am a lunatic for not using MBR? Thanks.
Hi David, your not lunatic or anything. I just proved that Grub in
F7 is buggy. I did this by doing what I had been trying all morning on
F7 in one sinple thing on FC6. It works fine now :-)
If you have an old FC6 on your computer try it there. It will work.
