[syslinux] loading any size image file, why?

[David Walker]

I'm sorry if I seemed a bit newb, but that isn't what I was looking for, I
know the c h and s mean, but I was wondering, as far as memdisk is
concerned, what do those values mean to it, I always use the same values of
c=255 h=2 s=36 floppy, but if I load a 4500k image or a 28000k image, those
values don’t change a thing in the image what significance do these values
have in the actuall memdisk program.

As for ghost I use ghost 2003, I do not do much ghosting of linux machines
as all ours are winxp Ive looked into g4l before, but I don’t think my co
workers would go for this when there used to the interface of ghost.

c=cylindars same as tracks
h= heads
s=sectors per track
c*h*s* 1/2K gives total size. Number of 512 btye sectors.

Just wondering what ghost you are referring to, is that Norton Ghost or one
of the other versions. I used norton ghost before, but it doesn't work with
systems with Fedora Core 3 or above, unless you do a sector by sector copy,
which makes much larger images, and takes longer. I use g4l now, and have
used g4u in the past, but neither allows for resizing the images.
