FW: CERC ATA100 & Linux 2.6 Kernels..

This seems to be of an good option also, but then your limited to what you
can do because of the location of the 2 servers.. Poke around the Debian
Admin Site (www.debianadmin.com. There is an article on there that is a how
to, to do what Robert has sejusted. I remember reading it about 4 months
ago. If you have root acccess you can just push the files to the chrooted
/dir. Or

You can use yum to do this on a red hat system. maybe the Debian equivelent
(apt-get) may do this but not sure. ((never tried with apt)). 

Good Luck,
John

I have not heard of any good fixes for this.  These machines are kernel
locked until someone is willing to port the old driver to the newer kernels.
I have not heard of any willing for a small device that was avoided by many.
I have a couple in the field also running Debian Sarge.  The only thing I
can recommend if you must continue using the hardware as is would be to
strip the base install to the kernel only.  They you can install the current
debian version to a subdirectory and run all services from that subdirectory
using chroot.  Debian has many facilities for doing this.  This is how many
of their builds are done.  I have done this to release a server that can run
both sarge 32 bit and Etch 64 bit software without trouble.  It is not the
prettiest solution but neither is this particular hardware.  It would
provide you with updated userland software with support from
security.debian.org and with hardware support for the legacy controller.
Anyway, my 2 cents....
