Re: Linux + Adaptec 2940U2W = ??

["Christophe Renard" <lst_crenard mednet mc>]

Hi,

I've been using this kind of SCSI adapter for the last few weeks.

But I was unable to use it as boot device probably a combination of MILO,
ARC firmware bad will.

I had to install linux on an other HD, cook a new kernel including the
Adaptec driver and change my ARC/MILO boot options and the /etc/fstab
accordingly.

The new adapter is recognized but what has to be taken into consideration is
that including the driver in the kernel may make /dev/sda become a disk
connected on the Adaptec card and /dev/sdb the original installation one.

I join a dmesg extract for details.

Hope this helps.

| Howdy folks,
|
| Does anyone out there know the magic recipe to get an Adaptec 2940U2W
| Ultra2 controller working in an Alpha (specifically, an AS 200 4/233)?
|
| MILO boots off the Red Hat 6.0 floppy just fine, but as soon as MILO
| loads the kernel off the kernel disk, the system freezes.  Once I remove
| the 2940U2W card and repeat the procedure, the kernel boots fine.  Replace
| the card, and the system locks on kernel bootup again.
|
| I'm running ARC 4.58.  I tried booting the 2940U2W card with its
| attached drive in a Pentium-class machine and it worked fine, so
| it doesn't appear that anything is broken.  Your thoughts?
|
| Thanks!
| Scott
