I know of no way, probing only with the PC & software, to determine which
type of X-1541 cable you might have. However, wiring diagrams for +all+
versions are freely available, and it shouldn't be any great effort to open
up and - with the help of a multimeter - examine a given cable and compare
it against the various arrangements.
The 1541-side parallel port is totally optional, and it is not required to
produce a working setup. However, when coupled with an appropriate cable,
drives equipped with the parallel connector operate several times faster
than even the fastest non-parallel setups. That said, any of the X-1541
setups will tend to run a fair bit faster than a genuine Commodre IEC bus,
so unless you plan to do a +lot+ of transfer, don't worry about going the
parallel route.

I do a fair amount of cross-C64 work, but all of

what I can tell you, much of which applies to MS/Win as well.
First you need a method of reading the original C-64 floppy into a .D64
(or
other supported) image. This requires +four+
basic things - a PC, a 1541
(or compatible) drive, a supporting software suite and one of the various
X-1541 cables. These days, with modern multi-tasking OSes, I'd suggest
using nothing but the XM-1541 cable design. These may be purchased, or,
with a little time & effort, built up by the DIY-er.
Does anyone know of a way, from Linux, to determine the particular
species of one of those cables? I bought mine years ago and no longer
remember which it is (and it isn't marked). I assume it's XM, since I'm
sure I intended it for use in Linux when I bought it, but I'd like to be
sure.
The XM-1541 cable connects the CBM 1541 drive to the parallel port on the
PC. The software suite (I highly suggest OpenCBM!) acts as a userland
driver / utility suite, allowing you to read, write, format etc. original
SS/SD disks on the 1541 drive. Once you have successfully read images of
the disk(s), then it's up to you how you handle them..
Somewhere I picked up the idea that for that you would need a cable that
connects, not only to the serial IEC port of the drive, but to a
parallel port which you must DIY on the drive. Would someone mind
chiming in here -- I don't understand how that would do anything other
than making the transfer faster? I know that on the software side you
specifically need nibbling tools, like mnib.
If you have one of the SD-based systems, simply copy over the image to
the
SD and you're good! I don't use SD card,
just original 1541 & floppies,
so
wouldn't have much help for that end of the
process. But I'm sure it's
very
well documented by the vendor of the SD-card
drive hardware - right? =)
The SD card devices all use Ingo Korb's SD2IEC software, as far as I
know. The main source of documentation I know of is at
<https://www.sd2iec.de/gitweb/?p=sd2iec.git;a=blob;f=README;hb=HEAD>.
