Received the modified BIOS for the Tyan Tiger 133 (S1834D) by Mentat-vvo. First run works well. Intel Pentium Pro (black 1mb version) meets the VIA Apollo Pro 133A chipset. Will do the B21 trick for 100MHz fsb now and I waiting for a GeForce 7600 GS 😅 Good. But, the best performing mixture of video …

So this happened last night :D Congrats! I saw you were able to reach 5700 on YouTube. Thanks for hires photo of your mobo. Maybe those jumpers are enough to switch the bios and chipset to 1MB cache. I also have turbo-tag sram IC that runs at 124M. Don’t have much time to mess with this stuff …

Do they work in dual CPU mode? I think test runs in single CPU mode, but WinXP is definitely SMP-capable. The memory bandwidth Gain is the result of SDRAM overclocking to 146 MHz 2-2-2-6 and 2-way interleaving ON. There are the results of the same test with single CPU(512k) @ 95 MHz with Asus P3V4X …

So just use a EEPROM flasher to flash it back to the stock and/or reflash it with the modified BIOS. I wouldn't necessarily just junk the board because of a bad flash. I don’t give a junk )) Stock bios was wasted by awdflash) I’ve found some bios and will try Plus CPUs with it tomorrow. Update: …

Sad news, guys. The 3.3v support in OR840 has beed wiped out. I was expecting this trick from Intel. The PPro CPU just do not allow the mobo to start. Though battery trick helped to turn back normal power sequence , the board locks with 88 code with P3-450 & P3-667.
