Dead(?) BIOS for Viglen 486 PCI 2 m/b?

Recommended by Wim's BIOS...

Hi ALL!
I have a problem with my old Viglen 486 PCI 2 motherboard,
manual MA-6452-OB-02, part number 4D57638 (with bar code),
s/n 4075394 (as is).
Also I fond on the top of m/b: DT PCI2.

After turning on power I hear 1-2-2-3 beeps. I mean it is BIOS checksum
error. (I visited Phoenix site to consult).
I tried to find BIOS on the web and Viglen site, but can't find such motherboard and right BIOS (according description). Viglen's tech support tell me that they haven't such BIOS too....

Inside file of BIOS I fond this information:
NCR 53C810 SCSI (PCI 2.0G DSR) 07/19/93
NCR SDMS (TM) V3.0 PCI SCSI BIOS, PCI Rev. 2.0
v4.02 Copyright 1992-93 Phoenix Technologies, Ltd.

Can you help me find BIOS file or/and send it to me by e-mail: era101@chat.ru ?
Or may be, you have a newest version of BIOS, without Y2k problem and
with large size hard drive support?
Sorry for poor English and thanks.

Email Viglen tech support with all the info. Chances are you will receive the bios if they still have it. I have two DT-PCI boards (manual MA-6452-OA-02) for which they gave me the complete manual after I emailed them.
