Error Reading Disk with GAG Boot Manager

I recently installed MEPIS on my computer's second hard drive and loaded GRUB on the root directory of MEPIS instead of loading GRUB on the MBR. My goal is to use the GAG Boot Manager to boot MEPIS from a floppy disk. I downloaded the GAG zip file in Windows 2000 Professional, unpacked the files, and made a bootable floppy disk with GAG loaded on it.

When I start the computer with the floppy disk, and after the BIOS checks are complete, the word "GAG" briefly appears in the upper left corner of the screen followed by a green "error reading disk" message. Then the computer hangs. I tried copying GAG onto 3 separate floppy disks with the same result. I'm unable to read the contents of the floppy disk because it apparently uses a file structure that neither DOS nor Windows recognizes. (When I click on the floppy in the Windows file manager, I get a message saying that the floppy isn't formatted.) However, I suspect the "error reading disk" message during boot is telling me there is an error reading my hard drives -- not an error reading the floppy. There are no other diagnostic messages other than "error reading disk."

Both IDE hard drives are on the same IDE controller. HD0 is 30GB and has two FAT32 partitions with Windows 2000 on the second logical partition. (The first primary partion once had a legacy Windows98 OS that is now dormant. That's another long story.)

HD1 is 120GB and has five partions: a primary NTFS partition for data, a logical NTFS partition for the Windows page file, and Linux logical partitions for /root/ and /home/ plus a Linux swap partition.

Has anyone else had the same error message when using the GAG Boot Manager or have any idea what might be causing this? Could the NTFS partitions on HD1 be messing things up? Or possibly having two hard drives on the same controller?

I tried Smart Boot Manager, which also runs from a bootable floppy disk, and SBM is able to access all of the partitions on both of my hard drives. However, I really prefer GAG's user interface and I would like to get GAG to run if that's possible.
