Hi Felix, the FORCELBA option has no influence on the boot sector:
It belongs to the "modify config flags in the kernel file" feature set of SYS instead. So only AFTER the boot sector loads a kernel, FORCELBA applied to the kernel would have the effect that the kernel always uses LBA to access FAT partitions on disks for which the BIOS supports any LBA. If you want to force SYS to put a LBA-only boot sector on your partition, you have to use other options. Also, not all versions of our SYS let you force this. "FreeDOS SYS for Linux" does let you force such settings, by the way: http://ericauer.cosmodata.virtuaserver.com.br/soft/specials/sys-freedos-linux.zip In general, if you want special SYS options, do not rely on FORMAT /S, but simply call SYS manually after FORMAT. Note that if CHS geometries of ?x32x33 and ?x64x32 both are a bit odd, maybe you can give some more details. Why for example is the "first primary" not C: for XP? And do you want to boot XP, DOS or both from that partition? If both, then you have to use a boot menu and probably have to store the separate boot sectors for (both?) operating systems in files which you can then add to your boot menu. Whether you want to force kernel and/or boot sector to use LBA or a certain CHS geometry of course depends on how far in the boot process you already get with default settings.
