OK, so I have gathered all the necessary steps/elements that should make a PCMCIA CF to work properly in an Amiga system:
1) PCMCIA Adapter (older, 16bith version)
2) CF card
3) Following this guide
here.
4) cfd.lha version
1.275)
fat95.lha 6)
CardReset v3.07) Formatting the CF card in FAT or FAT32

I need some entries in my startup-sequence. I am not certain about those.
My Progress:
1) I know my PCMCIA Adapter is a
compatible one, so
this first step is OK.
2) I have TWO CF cards, one is KINGSTON 4GB 9904318-030.A00LF (5282907-0356683) 2008 and the other one is an older CANON (came with my 2005 CANON Digital camera) FC-32MH 32MB Made in Japan
(I need some confirmation on this step, since either of them could be the issues here)3) Then I simply followed this guide
here, and it was successful, (in a sense that I did not see any error message), and all the files/folders 'seem' to be in the correct places.
4) I downloaded cfd.lha version
1.27,
5)
fat95.lha 6)
CardReset v3.0 and installed them in the correct places.
7) I have indeed formatted my CF cards using a DOS command on an XP PC by using the following command: format f: /FS:FAT (f: being my CF drive letter)

What needs to be inserted into my startup-sequence.?
At this point, the reason my A600HD does not see the CF card should either be to an incompatible CF card (unlikely) or something else.
What gives?
These are other resources that I have asked/consulted for help:

Make sure you've got the following:
compactflash.device in DEVS:
fat95 in L:
CF0 in DEVS:DOSDrivers/ (if you want to mount it automatically each boot)
or SYS:Storage/DOSDrivers/ (if you want to do it manually by clicking on the icon or typing 'mount CF0:' in a shell)
If this fails, have a look at CardReset and CardPatch (there's a bug in the way A1200s handle the PCMCIA port, these proggies try to remedy that)
Both should go in your startup-sequence.
I am asking him: Both should HOW go into my startup-sequence?

Just install CardPatch from Aminet and insert before your SetPatch line in Startup-Sequence the following lines:
FailAt 11
C:CardPatch
Also... if you installed all the neccesary files, you can check via HDToolBox using the Compactflash.device that the CF is regognised by the system as well.
