RE: [PLUG] Kernel issues


Actually with SuSe, I wouldn't need to hack the install CD at
all since it already includes a kernel with the acpi patch.
Isn't the free ftp install just a test system, without all the
"bells and whistles"? Are you using SuSe 8.1? Comments?

As for support, I telephoned RH--since I purchased RH 7.3 and
8.0 I'm eligible for support--and was told they don't support
my particular model laptop. I thought I was talking to M$! I
was very surprised by their lack of willingness to address a new,
yet increasing problem--the new power management standard for many
laptop manufacturers, acpi. A good friend of mine--until just a
few months ago--worked for RH as a developer. He's the one that
got me so hooked on Linux and OS software. But that's another
issue that I don't want to get into...I'm trying to stay on track.

I haven't tried using the CD in rescue mode to work through the
problem. I don't have any experience with that so I'll have to do
so reading and give it a try. Whatever boot image I use will have
to be CD-ROM since the laptop doesn't come with a floppy drive--
although they offer a USB floppy drive I chose not to purchase it.

I appreciate your thoughts. Thank you.

There's always the free ftp install of SuSE from
http://www.suse.com/us/private/download/suse_linux/index.html.  It's up
to 8.1 now.

Having said that, I think it's possible to make an install disk for SuSE
with a different kernel if you need to.  I haven't had to, although a
laptop I installed on only boots from older SuSE install disks, so I
used them instead of the present install disks when I did an upgrade...

RedHat may support the same thing, but my RH experience is very limited.

The general idea is:
- find a kernel and supporting modules that is known to work on your
laptop.
- create a boot/install floppy with that kernel.
- Once booted, point the installer at the version of RH/SuSE you want to
install from CD/ftp/etc.
- If, after the install, the kernel won't boot the laptop, replace the
kernel using your boot/install cd in repair mode.

Call RH support?  Purchasing SuSE includes install support for 30 or 90
days, depending on version.  Does RH offer the same?  Also, the SuSE
hardware database is online, so you can check in advance to see what
they say about compatibility.
