Problem with UM9008F

[Spider]

Hi all. I don' know Deutsch language and can't read forum
Can anybody help me?

I have assembled WebServer based on ATmega32 and ISA NetWork Card based UM9008F chip (I can't find RTL8019 based).

After power up in Terminal I see ERROR(255). I have change rtl8019.c to next view:

	ReadRTL (RSTPORT);

	WriteRTL (DCR , DCRVAL);
	WriteRTL (CR , (1<<STA| 1<<RD2));
	printf ("ISR: 0x%x\n",ReadRTL(ISR));
	WriteRTL (ISR ,(1<<PRX|1<<PTX|1<<RXE|1<<TXE|1<<OVW|1<<CNT|1<<RDC|1<<RST));

	//startet die Network Card
	WriteRTL (CR ,(1<<STA| 1<<RD2));
    DATA_PORT_RLT_WRITE = 255; //Schreibt eine 255 auf den BUS
}

and this give next result:

I had to poll the ISA bus signal IO CH RDY to get the UM9008 to work. If done, it works fine though.

I did not find a way to work with delays in the register access functions, they were either too small or large enough to disturb the UM9008 (especially in case of the the ISR).

PIN 70 at DM9008. The signal is SLOT.
On my card the pin was pulled high. (= 16 bit mode)
After removing the resistor SLOT is now LOW (= 8 bit bode) and now the ping works! (Essential to consider "Ethernet.zip" from A.K. !)
