As I wrote, I haven't currently a 810 rev < 15 installed on my home
machine and I did the testing by hacking the driver device tables for
a 810a and a 895 to be driven by the NCR generic firmware instead.
I have a machine at work under FreeBSD with a 810 rev. 2 and it is planned
to test the driver on this machine on next tuesday.
Looking into the detection code, I see no obvious reason for the driver
not to accept your controller. If you have time for, you may add some
`printf' in sym_find_pci_chip() and sym_find_firmware() in order to track
the problem.
sym_find_pci_chip() detection loop:
-----------------------------------
Printing device ids and revisions ids before the `if's can help.
...
for (i = 0; i < sym_pci_num_devs; i++) {
chip = &sym_pci_dev_table[i];
if (device_id != chip->device_id)
continue;
if (revision > chip->revision_id)
continue;
return chip;
}
...
sym_find_firmware is a pretty trivial function.
-----------------------------------------------
/*
* Find the most appropriate firmware for a chip.
*/
static struct sym_fw *
sym_find_firmware(struct sym_pci_chip *chip)
{
if (chip->features & FE_LDSTR)
return &sym_fw2;
#ifdef SYM_CONF_GENERIC_SUPPORT
else if (!(chip->features & (FE_PFEN|FE_NOPM|FE_64BIT)))
return &sym_fw1;
#endif
else
return 0;
}
