Fedora Linux on the Sharp M4000 notebook

This page contains some brief notes about my experiences getting Fedora 8 Linux working on my Sharp M4000 laptop. A previous page about Fedora 6 on this machine is here.

Here is a brief summary of what's working on this machine. (Basically everything is, except that I haven't tried the modem.)

Basically Fedora runs pretty nicely on this machine. A few small tricks are needed as described here. Complete installation should take you about an hour.

As usual, these notes are merely a document of things that worked for me. There's no guarantee they will work for you, and there are some things you could do while installing Linux that would really mess up your computer bad. I'm not aware of anything that will do that other than flashing your BIOS, which I don't recommend, but hey, you never know. You have been warned. All opinions expressed here are those of the author and are not necessarily shared by the University of Michigan.

Installation

The machine came with Windows XP Professional. I wanted to keep that, so I resized the Windows partition, as described in many other places. There are many tools you can use for this (parted, gparted, qtparted, Partition Magic). I used the free GParted Live, which did the job fine.

Windows came in a 60GB NTFS partition, which I resized to 15GB. There was another empty 10GB NTFS partition, which I deleted. Also there was a 5GB FAT partition. This partition contains an entire spare copy of Windows XP, in case you need to reinstall Windows. (Sharp provides this instead of a Windows CD.) The standard boot loader on the computer can reinstall Windows for you from this partition. (I think you hit F10.) However, installing Linux overwrites the standard boot loader with the Linux boot loader, which means you will no longer be able to reinstall Windows this way after you have installed Linux. To get around this, you can make a Windows recovery disk (actually four CDs), which as far as I know contains a complete copy of what's in the utility partition, and allows you to reinstall Windows at any later time. To create a recovery disk, get four blank CDs, boot Windows, and then follow the instructions contained in the computer manual. Once you create a recovery disk the reinstall-Windows-from-hard-disk-partition option is disabled anyway, so you might as well delete the utility partition, which is what I did, or you can reinstall Windows from the recovery disk, which deletes the partition for you.

This left me with 65GB of free space for Linux.

I did a network install using the basic boot CD, but installing from DVD should be very similar. I had to change the boot order in the BIOS to get the machine to boot from the CD drive – hit F2 as the computer is booting and use common sense. Then stick the disk in the drive and fire it up.

For some reason the Fedora 8 installer hangs on this computer, but there is a simple fix: edit the boot options on first start-up and add the options floppy.allowed_drive_mask=0 clocksource=acpi_pm. I have no idea why this works – neither option sounds particularly promising – but various people found that this works on other computers and it does with this one too.

After that things proceed as normal. When you get to the part about partitioning the disk, you can accept the default partitioning or you may want to do a manual partitioning yourself, which is what I did. I made a 100MB /boot partition on /dev/sda2, a 1GB swap partition on /dev/sda3, and then an extended partition holding 10GB for / and the rest on /home.

The installer will also ask you about the boot loader. At this point click the advanced options box, and when you get the advanced options screen there's a box for general kernel options. Here you should type ide0=noprobe ide1=noprobe. Without this, the DVD-ROM drive doesn't work properly.

The rest of the installation is vanilla. When it's done installing it'll reboot and the first time it boots it will run through some setup stuff – creating a user account and so forth. After that you're done! Congratulations. You've installed Linux.

Tricks


That's about it. Overall, I really like this machine – it's very nice to use, has an excellent screen, it's fast, light, and well designed. I'd certainly recommend it if you're looking for a sleek and portable Linux machine.
