Hello,

after I compiled my kernel (2.6.19-gentoo-r5) with "Device Drivers - ATA[...] - PCI IDE Chipset support VIA 82cxxx" (needed for DMA) there is no /dev/hda entry for my DVD-RW.

The device is detected:

/var/log/messages

Apr 9 21:04:51 fusel hda: _NEC DVD_RW ND-4550A, ATAPI CD/DVD-ROM drive
Apr 9 21:04:51 fusel ide0 at 0x1f0-0x1f7,0x3f6 on irq 14[/code]

[quote]# cat /proc/ide/hda/settings
name value min max mode
---- ----- --- --- ----
current_speed 66 0 70 rw
init_speed 12 0 70 rw
io_32bit 1 0 3 rw
keepsettings 0 0 1 rw
nice1 1 0 1 rw
number 0 0 3 rw
pio_mode write-only 0 255 w
unmaskirq 1 0 1 rw
using_dma 1 0 1 rw[/quote]

But /dev/hda does not exist. I think it has to do with udev, because there are some udev errors at boottime. But I cannot find them in the errorlogs.

Has anybody an idea what the problem could be?

Try /dev/sr0 instead... has something to do with ATAPI driver changes in the kernel...

What do you have in your ATAPI section and also your PATA-SATA section.

Since you are using the kernel 2.6.19, maybe you forgot to update your kernel properlly.

Hmm, I really forgot to enable ATAPI CDROM Support.

I didn't check this before, because I used my old .config and just added the VIA support. But obviously I getting older...

Thanks.

There a lot of changes between the 2.6.18 and the 2.6.19 Kernel.

In fact, the section ATAPI can be remove to use the new PATA-SATA section inside the 2.6.19 Kernel
