I'm trying to install Linux on a Compaq prosignia (EISA bus) which have a
build-in NCR 53c710 scsi controller. I know the IO (0x8000) address and IRQ
(15) but I cannot make it detected by Linux.
I tried the following override command with LILO : 'ncr53c710=0,0x8000,15'
but it is still not detected. Of course, my kernel is compiled with NCR
chipset enabled .... I also tried some dirty hardware-coded override, but
without success.
I tried to have a look in the driver code, and I saw the following in
53c7,8xx.c function normal_init :
switch (chip) {
case 825:
case 820:
case 815:
case 810:
schedule_size = (tpnt->can_queue + 1) * 8 /* JUMP instruction size
*/;
script_len = NCR53c8xx_script_len;
dsa_len = NCR53c8xx_dsa_len;
options |= OPTION_INTFLY;
sprintf (chip_str, "NCR53c%d", chip);
break;
default:
printk("scsi-ncr53c7,8xx : unsupported SCSI chip %d\n", chip);
return -1;
}
This looks to me as if the 53c710 chipset is NOT supported by Linux. Am I
right ?
Thanks in advance
