That has been adequately explained  previously.

Only if that first 500 megs hasn't been used for something else, in this 
case the fix was to partition 300 megs as boot so this dumbassed bios 
could find it.

Not with this math crippled bios bearing a 2006 copyright. It MUST be 
wholly within the first couple hundred megabytes of the beginning of the 
disk or it can't find it, and it is the most recent bios available for 
an Asus M2N-SLI Deluxe motherboard, version 1701.

No. Without a /boot partition, just a directory entry, the installer is 
free to use that empty space, and the file system WILL use the available 
space for other things. This puts all the grub stuff, installed as the 
last thing the installer does, way too far into the disk for old bios's 
to find.  Your version of a "legacy" bios is a snapshot taken a month 
before UEFI became the M$ dictatorial law. I go back another 40 years 
into the '70's. I go back far enough I've dragged management into my 
office to show them how a computer should work, running os9 on a trs-80 
color computer, multiuser, multitasking, when they were still running 
dos-2.1 on their 8086 boxes on their $2600 desks.

But no one ever got fired for buying I've Been Moved boxes...

Once in a while, the old man is right.
