PXELINUX has no such 32 MB limitation (it pretty much implies a bug in 
either GRUB or your TFTP server.)

Great it worked. What I did to get a 114meg image (win partition is 105meg) as 
my drive is 20gig

dd if=/dev/hda of=winimage.img bs=1024 count=117184

Thx for you quick response. And your great software!! it really is a life save
for us.
