Intel Pro 1000/PT 1xPort->2xPort

Попала в руки данная карточка - (EXPI9400PTBLK) , однопортовая PCI-e 1x. Но на ней разведен 2й порт , не хватает только транса и мелочи в обвязку (кондеры , резисторы).

Никто не пробовал сделать 2х портовую , (если чип позволяет) , еще интересно узнать как она определяет сколько портов на ней присутствует , в EEPROM прошито?

Это будет всеравно ОДНА сетевка, просто со свичем.

Если память не изменяет - там плата одинаковая а чипы разные на 1 и 2х портовые варианты

Это одна физически плата с 2 портами, видится системой как 2 независимых сетевки. (в моем случае это eth4 и eth5)
