BAD NEWS: the L1-cache of the Tillamook is automatically DISABLED on booting by the BIOS :-( -> Speedsys returns a CPU-result of about the level of a 486DX2-50 (at 233 MHz Tillamook-speed). -> CheckCPU says "L1 Cache disabled", too. -> the L1 can be enabled with SetMul -> unfortunately it works …

Is there real no chance to get a multi of 4,5x to reach 300 MHz at 66 FSB?? I have an AIR 54TDP here with HX-chipset (Dual-Socket-7; https://stason.org/TULARC/pc/motherboards/A/ADVANCED-INTEGRATION-RESEARCH-INC-Pentium-54TDP.html) - it boots fine with L2 enabled and one or two (YEAHHH) Tillamook(s) …

Yes you can although I've never tried it myself. I could flash a chip for you but I need to find where I stored my chips. It also depends where you're from because the shipping cost may not be very interesting if you're too far (I'm in France). I’m in usa. You seem pretty experienced with it so if …

There were many standards and half standards, better to locate ground and +5 first from motherboard and check that first, because wrong placement of +5 or wrong polarity may fry your mouse, or motherboard. So I’m just going to have to map the board and the pigtail against the ps/2 standard mini din …

So apparently, you can use a nic with a socket as a programmer. https://www.ebay.com/itm/ENCORE-Gigabit-Ethernet-32-bit-NIC-Network-Adapter-10-100-1000Mbps/324295120087?epid=15009469191&_trkparms=ispr%3D1&hash=item4b817ed4d7:g:ZqEAAOSwvSJfX5XO&amdata=enc%3AAQAFAAACcBaobrjLl8XobRIiIML1V4Imu%252Fn% …

btw, off topic I have a extra switch on my "case" can I use it as a cmos reset switch? I tried putting it betweenthe NO positions of the clear jumper but the board acted weird until I put it back does this mean it needs to be a nc switch on the NC pins? or does it need to actually be a 3 pin …

[...] You can try that but are you willing to risk ruining the Tomcat ? Hotflashing is tricky and can ruin a good board... just my opinion. That's a bit FUDdy... I fully agree with darry (and others) that a programmer is a far, far better solution, and could kick myself I waited so long to buy one. …

I doubt there's an easy generic mod. You have to check to find a trace where your board sends the 3.3V to the CPU and cut there. The other components that need 3.3V won't be happy with 2.5V. Every board is different in layout. Exactly. It depends on the board´s layout. That´s why I had chosen the …
