Q: IDE->SATA adaptor

Q: IDE->SATA adaptor

[Eyal Lebedinsky]

I am still looking for a working setup for adding more SATA
disks to my machine. I acquired a small PCB that plugs into
the IDE socket on the mobo and provides two SATA sockets.

It worked out of the box, except that it only does udma2. Not
what I want.

If I try to set it to a higher mode I get the message
	hdc: Speed warnings UDMA 3/4/5 is not functional.

After some digging into the ide code I identified the problem
as 'id->hw_config' being zero. In two places it is checked
before allowing higher udma modes. One bit seems to be related
to the 80c (which has no meaning here and should probably
be hardwired on the board) and the other I am not sure.

I patched ide-iops.c to not check hw_config in the two funcs
where it does so:
	eighty_ninty_three
	ide_ata66_check


BTW my .config says:
	CONFIG_BLK_DEV_IDEDMA=y
	CONFIG_IDEDMA_IVB=y
	CONFIG_IDEDMA_AUTO=y

but the IVB is not enough here.


Does anyone know what is the correct way to get this adapter going without
a patch?


I should say that the disks do identify themselves correctly (see below)
but the kernel only accept some modes:

What IDE controller are you using?

I think specifying "ide0=ata66" on the kernel command line could help.

I do not think that it matters. ide0 sees its disks just
fine. ide1 had no problems in the past. It is only when the
adaptor is plugged in that this problem is seen. Nevertheless,
this is an ICH5:

0000:00:1f.1 IDE interface: Intel Corp. 82801EB/ER (ICH5/ICH5R) Ultra ATA 100 Storage Controller (rev 02)

I added 'ide1=ata66' and it did not help. I also got the messages:

Kernel command line: BOOT_IMAGE=2.6.14.3 ro root=306 console=ttyS0,38400 console=tty0 irqpoll ide1=ata66 single
ide_setup: ide1=ata66 -- OBSOLETE OPTION, WILL BE REMOVED SOON!
