>>> "I've read that, though DR-DOS supports FAT32"

EDR-DOS does, old DR-DOS doesn't.

>>> "some programs might not work fine."

Only old low-level HD utils. Don't care, use new ones. ;-)

>>> "is it possible to use LFN under FAT16?"

YES.

>>> "written the entries in the GRUB configuration file, menu.lst, which GRUB uses here to load the operating systems I have installed."

??? Ask GRUB guys ...

>>> "In adition, is it enough to unpack the EDR-DOS files onto a partition, or should I"

NO. Activate with "SYS.COM". But with GRUB ... ???
