The general idea is that sentences ending with a little hook sign, conventionally called "question mark" are actually questions:
Well which EXACT commands are you attempting to use in grub4dos?
How EXACTLY that "sony xmb intervideo instant on linux" (whatever it is) would boot "normally" (without grub4dos)?
for which it would be kind to have corresponding answers.
As well commands when issued on a command line (not inside a a menu.lst entry) produce feedback lines, which you should post, as sometimes they help in understanding what the issue is.
And finally try to describe WHAT actually you are after, WHERE you got the *whatever* you are trying to boot, WHERE (on whch hardware, etc.) it is intended to boot, WHERE (on which hardware, etc.) you are trying to boot it instead, etc., etc.
Right now you are providing not enough data to even start assisting you with your issue, what I posted earlier were - as stated - "general" advice/info on how a Linux kernel and initrd are loaded by grub4dos, but depending on a number of factors, including the hardware involved, the kind of media on which the files are and probably a zillion other factors there may be the need to add/change parameters (or even edit the contents of the initrd).
