 Posted: Fri Dec 02, 2005 6:43 pm Post subject: IDE Controller Card Issues? |
 |
|
Hello!
I just moved an older (ATA 100) 2 channel IDE Controller card w/ three largish HD's from another computer to this one.
First issue - on boot, when it does the Controller Card BIOS thing and shows you the drives, they're all at like 130 something GB's (they're really like 160,200,250)
Second issue - no /dev/hdx objects for them
It supported the large disks before, on my other computer..

Negated Void,
The drives are probably seen as 137Gb, since there is a LBA limit there.
Its not a problem to Linux, although you may need the stroke kernel option.
Depending on your kernel, there is a config option called IDE stroke or a kernel command line opdion (whose syntax I don't recall) that allows Linux to see the whole drive.
The /dev/hdX objects should be created by udev correctly.
Does dmesg show ide2 and ide3 being probed correctly ?

It seems that the error was that i hadn't compiled in kernel support for the specific chipset (Promise something) on the IDE Controller card - I'm supprised that the generic stuff didn't support it though.
Apparently, with that compiled in, Linux can break the 137GB limit. The BIOS, on boot (which is all i could see before) still displays them as smaller, but cfdisk and stuff all report them as their full size.
Thanks for the help!

The generic driver can only deal with IDE controllers in legacy mode (ie the ones that use the standard IDE I/O ports - usually only the one in your chipset, sometimes also other controllers on the motherboard). PCI cards run in native mode, and need their specific driver (while legacy mode is standard, native mode requires the driver to know about the specific chip's register layout, so the generic won't work).

The controller card BIOS is probably a bit old and doesn't understand LBA48. Not a problem, as long as you don't put your /boot at the end of a drive. |
