I've always meant to try it out, but can't remember having ever done so. 
  The "initrd=xxx,yyy" logic wants to make sure that each chunk is padded at the end to a 4-byte boundary, but since typical disk sectors are 512 bytes, that means no padding is required, so all the pieces should just fit together as an indistinguishable whole HDD image, as far as MEMDISK is concerned.  Compressed pieces won't work, however.

So please report your results. :)

The incomplete Windows version is sitting here on my computer. :(  The priority isn't high enough on the to-do list just now, I'm afraid. 
Please check again in a month.

You're asking about wimboot, which is relatively new, and using it with Syslinux, for which patches were submitted this morning but haven't been merged yet, as far as I know.  A patch for wimboot is pending, too.  If these patches are accepted, then someone can write a guide for using wimboot with Syslinux.  Right now, that might be a premature effort.

You're welcome, I'm sure.
