BIOS with ID string 04/01/96-UMC-881E/886B-2A4X5000C-00 (the original manufacturer ID is carefully hidden). I have found another identical board with a string of 2A4X5T1B and marked TB-486-OB, so this board was made by Trangg Bow (AKA Taemung or Fentech).

He has also made this EASY HTML MANUAL. Thank you Pavel :)
