[rescue] file to boot xyplex 1600

[M A]

Hi!
 I have a xyplex 1600 and I'm booting it using tftp.
I'm using file mx1500.sys.
My problem is:
- I don't have access to flash card, I receive a
message:
Xyplex - Memory Card Feature disabled
I guess because I didn't load mcffs1.sys file.
- How can I load this file from a tftp server ?
- How do I copy mx1500.sys file and mcffs1.sys to
flash card (flash card is disable)and boot from flash
?
- Is mx1500.sys is the correct file to be used with
xyplex 1600 (4mbytes) ? How about mx1600.sys ??
- If not, does anyone can send this right file to me ?

Thanks
