When i try send a package in bochs,get the following error

[Cobbage]

When set the CR send command i will get the following error message：

00167863831p[NE2K ] >>PANIC<< CR write - tx start, tx bytes == 0
00167882994e[NE2K ] CR write, tx timer still active

And then test the cr register reg0&0x04 always true

I have no experience with the NE2000, but the error message makes it obvious you are trying to send nothing.

What have you done to verify that?

when i set the TCR(value=E2) register loopback model,i can get the package from receive buffer.

But when i set the TCR(value=E0) register normal model,this error occurs.
I test through the register.
after write data set CR register send command 0x1E
get CR value but the result is 0x1E should 0x1A
get TSR value...................is 0x01
get ISR value...................is 0x42
