Which of course is NOT needed if you use memdisk, grub4dos or both for booting to a RAM disk.
Now, something for Mike:
I got the 1.44 floppy image from working "often" to always! The key is RAMFS.SYS, included in various Panasonic USB packages, for example this one. A simple DEVICE[HIGH]=RAMFD.SYS copies the boot image to a XMS Ramdrive, and mounts it in-place (normal Ramdrives still work). Step 2 would be to add RAMFD.SYS in Windows' IOS.INI - works for me.
