Pentium III 1000E (Coppermine-256) started successfully, without any modifications required.
Tualatin did not started, VCORE = 1.3VDC measured, no boot.
Modification in progress:
1. Изолировать ножки процессора: AN3 (DYN_OE), AJ3 (RESET#2).
2. Изолировать AK4 и соединить его с AK26: VttPWRGD route to 1.5V from AN11 via 1Kohm
3. Соединить AM34 и AK36. (VID25mv)
4. Изолировать ножки: G35, G37 и N37.
5. Cоединить: G35,G37 и N37 вместе.
Now CPU working fine, 100MHz FSB * 10.5 ratio = 1050MHz @ 1.45V
Scope upgrade complete, no other plans.
