Where did you see this? (I'd like to know, to read about it more.)
Are you sure it was not a reference to Linux on the Alpha (DEC chip fame)
and not alpha-software?

In Linux, examine inclusion of the "vfat" module to mount fat32 based
partitions.

I have used it for many years (Windows 95-Windows 2000) and it has worked
well for me as a filesystem type to get files between both OS as each are
booted on the same machine.

With Windows NT, came the feature of 4GB root filesystems on FAT16.
Wasteful, but possible. NTFS was a better choice for security, but not so
great for a dual boot NT4/Linux system where files from NT4's boot volume
would be wanted. A shared extra FAT16 partition (1GB) was a good middle
ground if you needed NTFS for other stuff.

Windows 2000, has it better with more FS support and Linux, but worse with
NTFS support and linux.

Yep. The Max MS permits for FAT.

Linux has no problem with 4GB FAT16 partitions, AFAIK, and you seem to
show this to still be the case. It is just inefficient, as the minimum
filesize (even for empty files) is rather huge, and wasteful.
