I have seen posted  ( perhaps on SIMTEL20 ) source for a V20 compatible
XT bios. I have used it on one PC clone and it works. Here it is from
MSDOS.SYSUTL :
wilker@hopf> arc -v bios-asm.arc

Re:   BIOS Musings

You may be interested in a history of where this BIOS came from, and
how it arrived in its present form.  A heavily patched,
partially-functionally BIOS (with no copyright statement, or other
visible indication of origin) was supplied with my IBM-PC/xt
compatible 10 mHz motherboard.  In order to get my motherboard to
function correctly, in other words, to work with the parity interrupt
enabled and to operate with the NEC "V20", it was necessary to
disassemble and thoroughly go thru this "anonymous" bios, which was
hinted as supplied by Taiwan, while limping along on a name brand
bios, as supplied on my previous motherboard by a different vendor.
