You may need to determine exactly which type of BIOS EPROM or EEPROM you have before using the programmer.

Usually, this is printed on underneath any BIOS manufacturer stickers.

Tip: If you care about preserving the sticker, don't use a razor blade to lift it up. You'll cut the label 100% of the time and wish you hadn't. Just accept that it's going to crease a little bit.

  1. Boot the VM and make sure everything works
  2. Install Xgpro if needed, then connect the programmer
  3. Remove the BIOS chip from the socket of the mainboard
  4. Install it in the programmer
  5. Read the top of the chip and select the matching type in XDG
  6. Connect the TL866-II to a USB 2.0 port, it draws some current, so low power ports won't work
  7. Select your chip
  8. Install the chip into the programmer as shown on the display
  9. Read the chip (READ button)
  10. Save the results to a .bin and copy to USB, FTP, etc. (SAVE button)
  11. Load the .bin into the Windows 98 VM
  12. Run bp p2b.bin /m to select which patches you want
  13. Move the patched file to your TL866-II programmer and load it
  14. Write to the chip (PROG button)
  15. Reinstall into the motherboard
  16. Test

BIOS Patcher retains a copy of the original modules as a backup. To load them instead of the patched BIOS, do either of the following:

An extensive manual for BIOS Patcher (BP.EXE) exists in English in About_BP.TXT, so I won't reproduce it here.

 BIOS Patcher ver. 4.23.
Attention! Advanced qualification is required!


===============================================================================
To run BIOS Patcher type: "bp patch_file [options]"
Options:
/c - manual add CPU Name (will be displayed for ALL CPUs!)
/d - not delete tmp-files
/e - show extended info (like using "cbrom.exe /d", without patching)
/h - this "help-screen"
/g - skip delete BIOS CGA-font 8x8 (increase size of modul.tmp)
/k - select multiplayer for VIA C3 processor: "/k3.5"=3.5x, "/k12"=12x etc
/m - manually select items for patching (default - search/patching all puncts)
/o - change "original.tmp" to another file (N/A at the moment - in development)
/p - try add "+PCI" -option (RAM_freq > CPU_freq) to VIA 693A/694X/694T
/s - remove "backup" -key (virtual dual-BIOS feature)
/v - RAM-tweak for Pentium1/2/3 with VIA-based MB
/u - "ultrapack": packs 2Mbit/4Mbit-BIOS to 1Mbit (N/A - in development)
/x - display real frequency for AMD Athlon XP processors
Example: "bp 6130.bin /e"
         "bp 6via86p.bin /p/c/k8.5/d"
===============================================================================

if you can`t see all messages - choose 80x50 mode or run with ">report.txt".

/c - force name of CPU (it will be shown for ANY CPU PLUGGED INTO THIS BOARD)
/d - don't delete temporary files
/e - show rom file info. This is like cbrom.exe /d (only info and no patch)
/h - help
/m - manual choosing of things to patch. By default patcher fixes all errors.
/p - add "+PCI" (RAM_freq>CPU_freq) for VIA 693A/694X/694T (testing)
/s - turn off roll back
/v - overcloking (speed optimization) of memory for VIA-based motherboards P1/P2/P3 (testing)
