I am no IRQ nor an NIC expert, but you seem to have an NE1000 card.
This is an 8 bit ISA card.
I vaguely remember that 8 bits ISA cards can acces only the lower
half of your IRQ's and are often set at IRQ 3.
Could it be possibe that your cards responed to a probe on IRQ 10,
but actually is located on IRQ #3? (afterall IRQ 2== IRQ 9, which
someone with more knowledge may explain in detail )

Setting all IRQ's to legacy prevents any plug and pryt card to get
an interrupt! You are now forcing these cards to fail.

Which is _not_ valid.

Tx stand for transmission. I am guessing here, but
1 The network laye handles to NIC driver some data.
2 driver put packet in card
3 driver starts timer
4 driver tells card to transmit packet
5 card transmit packet
6 card generates interrupt
7 the drivers ISR, activated by the interrupt clears the timer and
removes ( the now succesfully sent ) packet from memory.
In your case the card does not deliver a suucesfull or recorgnised
interrupt, thus the ISR ( interuupt service routine ) does not get
called. Since it is not called it can not clear the timer.
Timer expires: error is generated.

What kind a card is this?
Ny Ne2000 ( ISA ) is at 0x300, an IO adress that is more then an
order of magnitute lower then your. Are you trying to use a PCI
or an ISA card?
