Well, I am successful . . .
. . . and thanks for your opinions and guidance. Now, how I did it:
I've been in contact w/ v-com (system commander's tech support). They were still clueless, with one exception. The one guy that's been there awhile remembered that both OS's had to start below 8192mb, or 8gigs. Well, I reimaged my machine and gave XP the first 6gigs, installed SCO, fdisk'ing to make the partition about the same size as the XP partition, rather than using rest of disk. (reason is, XP needs more space than SCO, will format other partitions later) After SCO completed, I was sort of amazed, syscom was originally installed on the XP part, but as usual was overwritten. SCO booted and I got to the BOOT: prompt and typed bootos ? which gave me two partitions to choose, then I chose bootos 3 corresponding to the NT/OS2 partition. The screen flickered off then on and XP's splash screen came up. It ran a checkdisk and needed to reboot, did the same process again, it came up just fine, everything worked. . . Booted to SCO, everything I set there up worked.
I bet it all comes back to that 1024 cylinder thing. The machine I am using is a 3 year gateway workstation, Pentium4, 1gigmem, Nvidia Quadro, 40gig hd. . . . according to the fdisk in SCO, everytime I went past the first 30 megs of the hardrive, I was surpassing the limit. . . well, INIT 13, that bios thingy, although not present in the bios, worked. I was able to boot both and get both to do their function. Also, edited /etc/default/boot for BOOT: prompt alias' to boot into XP.
Thanks Again!

boot.config
BOOT.CONFIG(5) BSD File Formats Manual BOOT.CONFIG(5) NAME
boot.config -- Configuration file for the boot blocks DESCRIPTION
The boot.config file contains options for the FreeBSD boot block code. When the FreeBSD boot loader runs, it searches the ``a'' slice of the boot partition for a boot.config file (as a result, slices which are missing an ``a'' partition require user intervention during the boot process). If the boot.config file is found, its contents are used as the default configuration options for the boot block code and are echoed to the system console. A valid format of this file is to put BIOS drive number, a controller type, a unit number, a partition, a kernel file name, and any other valid boot(8) option on a single line, as it is done at the ``boot:'' prompt. The options related to the boot image selection described below and all the other options available for boot.config are documented in detail in the boot(8) manual page. FILES
/boot.config parameters for the boot blocks (optional) EXAMPLES
The command: # echo "-P" > /boot.config will activate the serial console of FreeBSD. The command: # echo "1:ad(1,a)/boot/loader" > /boot.config will instruct the second stage of boot(8) on the first disk to boot with the third boot(8) stage from the second disk. The command: # echo "1:ad(1,a)/boot/loader -P" > /boot.config will do both of the above. SEE ALSO
