Ok, its strange that hd toolbox cant find your card(s).
I know that at least your 256Mb Sandisk card + 44-pin adapter should work (but not in a master-slave chain) because i have tested it myself.
Maybe it isnt compatible with all mainboard revisions if you cant get it working.
About the cd-rom and cf-card:
1.There is two options: use a Elbox splitter or Fast Ata (should work but i have not tested it myself).
DONT use a ide-fix adapter, because the software is not compatible with CF cards.
2.Use a Lexar CF card, at least i know 512Mb cards and less capacity works, those i have tested.
Set up a master-slave chain with the internal IDE interface and install for example the CD-Rom software included in OS3.5 or 3.9.
That works fine!
