SOLVED: Mitsumi CR-4802TE on 440LX motherboard

[Arthur Marsh <arthur.marsh@internode.on.net>]

Hi, after wondering for ages why I had problems with a Mitsumi CR-4802TE 
CD-RW drive not working reliably on a machine with a BIOSTAR M6TLC 
motherboard (Intel 440LX chipset, 266 MHz PII, 256 MiB RAM, running Sid 
with 2.6.17 kernel compiled for Pentium II at present) with the IDE 
interface speed automatically being detected as "Mode 3" for the CD-RW 
drive in the BIOS. I recently set:

/dev/hdc {
        dma = off
}

in /etc/hdparm.conf and was able to burn a CD-R successfully for the 
first time.

I have since changed the entry to:

/dev/hdc {
        io32_support = 3
        dma = off
}

but haven't tried writing a CD using this setting. Playback of an audio 
CD seems to work fine with this setting.

Is there a Linux hardware compatibility database that could give any 
clues on what settings to use for a given combination of IDE chipset and 
drive?

Arthur.
