[syslinux] Re: grub compatible

[Gregg Lebovitz]

Peter,

I appreciate you taking the time to answer my emails. I realize it may
be frustrating to have a random person ask you novice questions.

Looking at the grub code, it appears the 8192 limit in the code is
somewhat arbitrary. There appears to be more than enough buffer space to
support the 13.5K size you mentioned below.

I will pass this onto the grub folks. They may be willing to increase
the buffer to 13.5K in the released version.

As far as the changes go, I worked on the memdisk code because it gave
me an excuse to learn the i386 architecture and instruction set. If you
want to toss my changes, feel free.
