now that this has leaked onto the list,
the intel manual seems to indicate that the
check that's being tripped is using an undefined
bit in the register.*
i think the first change to try would be to comment
out the check, so
static int
at93c46r(Ctlr* ctlr)
{
ushort sum;
char rop[20];
int addr, areq, bits, data, eecd, i;
eecd = csr32r(ctlr, Eecd);
if(eecd & Spi){
print("igbe: SPI EEPROM access not implemented\n");
// return 0;
}
[...]

No.
I've done a dirty hack (temporary workaround), this helped me to solve
problem with connectivity.
This was temporary work and I've lost all changes. :(

Hello !
I have gotten "igbe: bad EEPROM checksum" message on my IBM (Lenovo) T61
Tablet.
I've took a look at NetBSD kernel sources (if_wm.c), that recommends to read
EEPROM twice :)
Comment from if_wm.c:
/*
* Read twice again because some PCI-e parts fail the
* first check due to the link being in sleep state.
*/
Maybe helpful :)

hello
i'm using 9atom on my pc but i have a problem with ethernet card, i
have these lines when the system start
igbe: SPI EEPROM access not implemented
igbe: bad EEPROM checksum - 0x0000
igbe: SPI EEPROM access not implemented
i tried to compile the kernel and try again but with the same error
pci | grep net ===> 2.1.0: net 02.00.00 8086/1019 10 0:e0100000
131072 2:000040 01 32
grep 1019 /sys/src/9/pc/etherigbe.c ====> i82547ei = (0x1019<<16)|
0x8086,
is there anyone have the same problem ? and how can i fix that if
possible
Thanks
