Trying to think about this, (correct me if I am wrong) the BIOS component must be functioning correctly: for me to see such an error message, i.e.Master Boot Code being read from first (XP) drive, followed by execution then being passed to second (OpenSuse) drive from which Grub Boot is beginning execution.
With only two drives (1st is PATA, 2nd is SATA) Boot functions successfully.
When I add a third drive:
Works OK if added unit is a SATA Drive.
Error 22, if added unit is a PATA Drive!
So it appears that, in the last (3rd Drive PATA) arrangement, Grub ceases to search for its files on its own disc, searching the newly added disc instead!
I have tried looking in the on-line Grub Tutorial, but did not see anything to indicate why this should be happening. I would be grateful if anyone can give me a steer on where to look for more information.

sdl_cdopen
SDL_CDOpen(3) SDL API Reference SDL_CDOpen(3)
NAME
SDL_CDOpen - Opens a CD-ROM drive for access.
SYNOPSIS
#include "SDL.h"
SDL_CD *SDL_CDOpen(int drive);
DESCRIPTION
Opens a CD-ROM drive for access. It returns a SDL_CD structure on success, or NULL if the drive was invalid or busy. This newly opened CD-
ROM becomes the default CD used when other CD functions are passed a NULL CD-ROM handle.
Drives are numbered starting with 0. Drive 0 is the system default CD-ROM.
EXAMPLES
SDL_CD *cdrom;
int cur_track;
int min, sec, frame;
SDL_Init(SDL_INIT_CDROM);
atexit(SDL_Quit);
/* Check for CD drives */
if(!SDL_CDNumDrives()){
/* None found */
fprintf(stderr, "No CDROM devices available
");
exit(-1);
}
/* Open the default drive */
cdrom=SDL_CDOpen(0);
/* Did if open? Check if cdrom is NULL */
if(!cdrom){
fprintf(stderr, "Couldn't open drive: %s
", SDL_GetError());
exit(-1);
}
/* Print Volume info */
printf("Name: %s
", SDL_CDName(0));
printf("Tracks: %d
", cdrom->numtracks);
for(cur_track=0;cur_track < cdrom->numtracks; cur_track++){
FRAMES_TO_MSF(cdrom->track[cur_track].length, &min, &sec, &frame);
printf(" Track %d: Length %d:%d
", cur_track, min, sec);
}
SDL_CDClose(cdrom);
