[syslinux] memdisk and OS/2

[Quinn]

Has anyone managed to get OS/2 to fully boot via Syslinux's memdisk?

I have played around with it a bit both as a floppy image and a hard 
disk image, but either it hangs when loading IBMINT13.I13 driver or 
doesn't load any .ADD driver and stops saying it cannot find COUNTRY.SYS 
(it needs at
least one .ADD disk driver loaded before it can continue accessing the 
boot device).

Going in details as far as I can see, it loads successfully the boot 
sector, OS2LDR, OS2KRNL, OS2LOGO, CONFIG.SYS
but stops there after attempting to find the correct .ADD driver to load 
in CONFIG.SYS.

I believe that the IBMINT13.I13 driver is the only way to go when it 
comes to using INT13h disk access (that is what memdisk does - redirect 
interrupt 13 calls to the ram disk it creates in memory) but if we 
cannot get the sources for this driver, then creating an alternate 
driver is the only way to go.

Is there an alternate Interrupt 13 driver for OS/2?

I have also looked into something that is also called memdisk by Veit 
Kannegieser.
His homepage is here: http://www-user.tu-cottbus.de/~kannegv/index_e.htm

You can get the program from here:
http://hobbes.nmsu.edu/cgi-bin/h-viewer?sh=1&fname=/pub/os2/util/startup/memdisk.zip

And even the sources for the program here:
http://www-user.tu-cottbus.de/~kannegv/quelle/memdisk.arj

It was a bit difficult to get Veit's memdisk up and running but I did 
somewhat manage to get a mini-OS/2 up and running in RAM. The 
dissadvantage with this program is that you cannot create directories 
during the creation of the ram disk and it is also limited to the amount 
of space of a floppy disk.

Is it possible to study the sources of Veit's memdisk program to create 
an alternate interrupt 13 driver for OS/2?
I would love to help although I am not a programming expert.
