Good day "tyuge",
I think you asked if Syslinux 4.00-pre1 supports FAT32.
Could you please describe your difficulty in some more detail? I am
under the impression that FAT32 is supported:
http://git.kernel.org/?p=boot/syslinux/syslinux.git;a=blob;f=core/fat.c;
h=3cf9594b5bdb74e12b12d4f89b394fad52597798;hb=db6bc6f4eb6a10fd4af96c5068
d651ad4aca95aa#l193
Note that the -pre1 suffix does suggest that it's under development and
there could be bugs. That and H. Peter's e-mail, where he notes that
it's a "development preview":

-pre2 is available now, too.
