[Etherboot-developers] 3c509 driver and the troublesome 486

[Timothy L. <tl...@ro...>]

Hi

In order to get the 3c509 driver to find the card on my 486, I need to
and the old DELAY function:

static void DELAY(int val)
{
    int c;
    for (c = 0; c < val; c += 20) {
	twiddle();
    }
}

and change get_eeprom_data as follows (changing the udelay to 60000 does
not help):

static int
get_eeprom_data(int id_port, int offset)
{
	int i, data = 0;
	outb(0x80 + offset, id_port);
	/* Do we really need this wait? Won't be noticeable anyway */
- udelay(10000);
+ DELAY(350);
	for (i = 0; i < 16; i++)
		data = (data << 1) | (inw(id_port) & 1);
	return (data);
}

Some time ago someone mentioned that perhaps currticks was not working
correctly on my 486.  How can I find out?  

Tim
