Is FreeLDR using a protected-mode call to read freeldr.ini?
I remember using the FreeLDR floppy image with Memdisk (a Syslinux
component, see
http://syslinux.zytor.com )
Memdisk is perfect for loading a floppy, and FreeLDR booted,
but could
not read freeldr.ini as it was not on fd0,
but on a virtual diskette (image) on ramdisk.
Just about the first thing that FreeLdr does is switch to protected mode. To
read from disk(ette) it temporarily drops down to real mode and issues an
int 0x13.
