I just tested installing the MerckManual demo version and I got it to work. You need to have this directory structure on your SD-1 card:
PALM/Launcher
PALM/Programs

I started the MerckManual demo install and followed it through until it told me to hotsync. I did not hotsync. I used WinSCP to copy the appropriate files to my SD card. I'm using WIndows XP, and I looked in C:\Program Files\Palm\ for the directory that stores my hotsync data. This is usually your LastNameFirstInitial. So for Push Wall the subdirectory was WallP. In this directory is a subdirectory called CardInst with a subdirectory named Slot-SD,....I moved all the files from this directory to the PALM/Launcher directory. Besides the CardInst directory there is a directory called Install,.....I moved all these files to the PALM directory. I then fired up GVM and ran a file directory utility called FileMan (you can use the freeware FileZ). I then moved the files I had moved into the PALM directory on SD-1 to RAM. I then exited totally out of GVM. I ran GVM again and the MerckManual icon was on the main menu which I launched. It seemed to pull up all the MerckManual index. I wasn't able to access any entries though since they are mostly locked in the demo. It looks like there is a beacon icon up at the top that you tap on to hotsync your serial number key with the Internet (be sure you have an Internet connection going on your tablet). I don't know if this will work for you, but give it try. It may not work since it looks like the program creates some type of extensive directory structure different than the one I mentioned. Good luck!
