Very Computer

I have an ASUS P4PE motherboard with an integrated Promise FastTrak376
(20376) controller. Controller is a RAID/SATA/ATA133 controller
capable of supporting some combination of one parallel ATA133 device
and 2 SATA devices.

I am currently running Linux 2.4.20 under RH8.0. I have a single EIDE
hard disk mounted off the standard EIDE controller connector in the
default RAID0 configuration (which of course doesn't mean anything for
a single drive).

I have tried some trivial modifications to the current kernel support
for earlier Promise RAID devices in a so far fruitless attempt to get
the controller and drive to work under Linux. Basically, I have
mimicked the support lines for the 20276 chipset based on the
simplistic assumption that the 20276 and 20376 may be somewhat
similar. [see below for list of my modifications]

The Promise controller does show up in /proc/pci as follows:

  Bus  2, device   4, function  0:
    RAID bus controller: PCI device 105a:3376 (Promise Technology, Inc.) (rev 2).
      IRQ 11.
      Master Capable.  Latency=96.  Min Gnt=4.Max Lat=18.
      I/O at 0xb400 [0xb43f].
      I/O at 0xb000 [0xb00f].
      I/O at 0xa800 [0xa87f].
      Non-prefetchable 32 bit memory at 0xe4800000 [0xe4800fff].
      Non-prefetchable 32 bit memory at 0xe4000000 [0xe401ffff].

However, no sign of it show up in /var/log/messages.

---------------
Here are my kernel additions. Each line is placed after the parallel analogous
line for the 20276 controller:

drivers/ide/ide-pci.c:
#define DEVID_PDC20376 ((ide_pci_devid_t){PCI_VENDOR_ID_PROMISE, PCI_DEVICE_ID_PROMISE_20376})

drivers/ide/ide-pci.c:
  {DEVID_PDC20376,"PDC20376",     PCI_PDC202XX, ATA66_PDC202XX, INIT_PDC202XX,  NULL,           {{0x00,0x00,0x00}, {0x00,0x00,0x00}},  OFF_BOARD,       0 },

drivers/ide/ide-pci.c:
          case PCI_DEVICE_ID_PROMISE_20376:

drivers/ide/ide-pci.c:
              IDE_PCI_DEVID_EQ(d->devid, DEVID_PDC20376) ||

drivers/ide/pdc202xx.c:
         case PCI_DEVICE_ID_PROMISE_20376:

drivers/ide/pdc202xx.c:
         case PCI_DEVICE_ID_PROMISE_20376:

drivers/ide/pdc202xx.c:
         case PCI_DEVICE_ID_PROMISE_20376:

drivers/ide/pdc202xx.c:
         case PCI_DEVICE_ID_PROMISE_20376:

drivers/pci/devlist.h:
  DEVICE(105a,3376,"PDC20376 IDE")

drivers/pci/pci.ids:
    3376  PDC20376 IDE

include/linux/pci_ids.h:
#define PCI_DEVICE_ID_PROMISE_20376     0x3376

----------------------------------------------

These changes didn't seem to make any difference to either the
/proc/pci entry or to the syslog startup messages. 'Fdisk -l' and
/proc/partitions obviously still doesn't show the disk.

Any thoughts on how to get this to work?
