Syslinux - Sep 2003 - Open file > 64 K in COM32

Hi all,

I used syslinux to load linux on DiskOnChip in PC104
for one embbeded project suceefully for several
months. But due to power lost sometime the image is
corrupted. I want to develop a COM32 util to check CRC
for the images and load the good ones. I read in the
comboot.doc that com32 can use read file SYSLINUX API
call to read a file, and the file must below 64K
limit. But the image files always bigger than 64K. So
anyone can guide me how to read this big files in
COM32 module.

There is no such limit.  You just can't read more than 64K *in one call*.
