Anybody manage to get UDMA 66/100 working with an on-board Promise 20267
chip?

Hardware: Tyan Tiger LE (with ServerWorks OSB4 _and_ Promise 20267 on-board)

Kernel: 2.4.3 with ide.2.4.3-p8.all.03242001.patch by Andre Hedrick (or
stock 2.4.3 with more or less same results)

FastTrack config: only 1 drive, configured as a SPAN volume consisting of 1
drive

I don't quite care about the Promise RAID features. I will use Linux
software RAID. The problem is that I cannot seem to be able to get the
controller into UDMA 4 (66 Mhz) mode!

I have enabled all the relevant DMA related kernel options. I have also
checked using the Seagate disk utility to make sure that the drive is
recognized (and configured) as UDMA 66 capable.

The following is from dmesg:

PCI: Found IRQ 10 for device 00:03.0
PDC20267: chipset revision 2
PDC20267: not 100% native mode: will probe irqs later
PDC20267: ROM enabled at 0xfeae0000
PDC20267: (U)DMA Burst Bit ENABLED Primary MASTER Mode Secondary MASTER
Mode.
PDC20267: neither IDE port enabled (BIOS)

I wonder what the last line meant by saying neither port is enabled?

be much much faster here]

Actually, upon further testing, I found that the MB will move on without an
Fasttrack array. However, it will proceed to boot from PXE because it now
thinks that there is no hard disk attached to the entire system (as reported
by the Promise RAID chip)!

So,

1. Promise driver doesn't support SMP or 2.4.x kernels

2. Linux IDE code won't support the chip in any Promise RAID config, not
even single disk span

3. If not under RAID config, the motherboard thinks it has no hard disk, so
booting from disk is not possible even though the kernel can run the disks
in ATA100 mode

The remaining alternative is to boot from floppy (to load the kernel) and
specify the hard disk as root disk... :-(

I am most disappointed with Promise (not so much with Tyan).
