From: "Frank Haber" 

I looked at an XP Home SP1 boot floppy #1.  It's a standard 512-byte-sector
1.4MB twin-FAT12 floppy, IDing itself as "MSDOS 5.0," but there's
no DOS on it.  The boot loader seems to be looking for NTLDR and
SETUPDLRBIN.

BTW, it won't boot on a 486DX2  (looking for CPUID function, etc.).  Damn
rights management (g).
