Can you imagine a sitation that at this point initrd.gz, a file needed
to be uncompressed to ramdisk, ist not found?

I cannot believe that this happens. Remember that the same vmlinuz and
initrd.gz start with eltorito from grub. isolinux would be made
responsible for doing something with high memory. No.

As I understand it, the isolinux.bin uses isolinux.cfg to show the 
content of the latter file by means of vesamenu.c32 on linux
framebuffer. This works perfectly.
Maybe that's not the whole story? I didn't think syslinux is in the way
when you boot by CD. 

Booting by syslinux from USB would be the next step in testing Slax,
when CD boot works. It's a little bit clumsy with this BIOS, you have to
press F8 early to get to the boot menu. Sorry, no experience with
syslinux on USB yet.
