I am trying to install xubuntu 6.06 desktop on my IBM Thinkpad 380ed, P166, 81m RAM and a 3 gig hd. I have run RH9, Slackware, and VictorLinux on it just fine.
The Xubuntu ISO cd boots just fine but yeilds the following error... ACPI: Unable to locate RSDP
Then Xubuntu seems to bypass the error and continues loading the essential files/drivers but then stops again with the following final message:
Uncompressing Linux... Ok, booting the kernel.
[4294667.296000] ACPI: Unable to locate RSDP
You weren't clear about if it actually boots? It's probably not a big deal (acpi-rsdp was probably compiled into the kernel, but your machine doesn't have it). If it stops booting, then the problem is probably not the acpi, but the very next thing that's supposed to happen. If it just hangs, give it awhile (I once had a kernel hang for over an hour before panicking! The thing is, I wansn't even expecting it to happen. I became caught up in other things, but still had the computer monitor in my view. Suddenly, I saw some new output being written to the console!).
Thanks for the help. I was not able to complete the Xubuntu install. I get this message pretty much right in the beginning what the Xubuntu ISO boot straps. The message allow Xubunto to continue loading various things but eventually stops before completing. The OS never completely finishes the install.
Maybe it's a problem in the BIOS? Did you try mucking around with different settings in there? Maybe completely disabling ACPI or making sure ACPI and APM aren't competing against each other?
ACPI is power control software and hardware for saving energy. Your machine may be old enough that it doesn't support ACPI which is part of the default install. There should be a way to install or boot without ACPI enabled. As an Ubuntu user I'm not sure what to do for Xubuntu.
I'll have to admit that I'm out of ideas. Maybe you could boot to one of the other distros, and then see the output of dmesg. Look for the part that gets stuck and what comes before and after it on your machine. For example, my boot sequnce has:
NOTE: I don't think this is going to help (it's a longshot).
Another thing you might do is check to see if the iso downloaded correctly (md5sum). You can also check to see that the image was burned correctly by extracting the image from the CD and doing an md5sum on that.
Some distros use the fact that you can have multiple kernel versions and a grub boot entry for each one. SuSE by default add a non-ACPI kernel option. You may have better luck looking into grubs boot parameters and then editing /boot/grub/menu.lst accordingly.
