In May 1999 I wanted a small PC to use as a simple network analyzer so I bought a Libretto 100CT. My aim was to install RedHat Linux 6.0 on this machine using the guidelines I had seen at various web pages on this subject. See the References section below.
Obviously I would never have started on this without the information generously provided by various people. Much of the information on this page duplicates info from other people’s pages in order to provide a complete story in one place. However this page doesn’t supercede those others. I recommend you read them too. They have used alternative approaches to at least some aspects this task. See References
This page documents how I went about the task of installing RedHat 6 on a Libretto 100CT.
Some areas that caused me difficulties were …
- The “hibernation” disk partition used for hibernation mode. My first install of RH6 trampled over it. My subsequent apm -S probably trashed swap. Anyway, I ended up reinstalling.
- The PCMCIA floppy disk drive is only good for booting the initial Linux boot disk. Since Linux doesnt have a driver for Libretto’s oddball floppy drive, I couldn’t load supplemental disks (for PCMCIA or Net support). The RedHat CD has separate boot-disk images that include pcmcia and networking but not as a single image?
- The NeoMagic video chipset was recognised but the video driver couldn’t be set up properly by the installer. That was not too bad, I deferred X until I had the initial installation completed. (no longer an issue with recent RedHat releases
- Shrinking Windows partitions I never have any luck shrinking Windows 9.x partitions with FIPS 1.5. I have tried this on several PCs. I suspect its because Windows’ disk-defragmenter regards some files as unmovable and hence leaves them at the far end of the partition. I always end up using Partition Magic.
- The Keyboard. At first it seems there is no way to key Ctrl+Alt+KeyPad-Plus or Ctrl+Alt+KeyPad-Minus because there is no obvious KeyPad-Plus key. These keys are used by XFree86 to switch video modes.
Before I got started, I gathered together the following items.
- Disk partitioning software. Something that can shrink a Windows 9x partition that hasn’t been perfectly defragged. Power Quest’s Partion Magic worked for me. It is commercial software. There are other commercial, shareware and open-source products that may work well.
- A PCMCIA Ethernet card or some other means of getting the contents of the RedHat CD into the Windows 9x disk partition. I used a 3Com 3c589.
- The XFCOM_Neomagic video driver. I obtained this from Red Hat’s FTP site
- Libretto Specs. I found it comforting to arm myself with the technical specs of the device. I found the IRQ’s used by the sound card using Windows 9.x. (environment variable BLASTER, control-panel/system) The Libretto manual has some handy stuff at the end. Toshiba publish some Libretto 100CT Specifications. I found the Adorable Toshiba Libretto page to be useful too.
- Driver for Floppy. Not needed for my installation. There is a beta driver for RedHat 5.2 at D Bateman’s FTP server. Since it is for RedHat 5.2 and involves kernel patches, I didn’t try it.
- Loadlin and initrd52.gz. Since I was not booting from the hard disk, I didn’t need LOADLIN.EXE, vmlinuz or initrd52.gz from Victor Gvirtsman’s site. Though it looks rather good, it’s only for RedHat 5.2 (at time of writing).
Installation of RedHat 6.0
I assembled my prerequisites. See above. I placed the Neomagic drivers etc on a suitable networked PC. Put the RedHat CD in the same PC
Made a RedHat 6 boot disk. This is documented on the RedHat CD. I could have done it from Linux or from DOS. From DOS, my CD-ROM drive is D: so I ran D:\dosutils\rawrite, told it the disk image file is D:\images\boot.img. From Linux, I used dd if=/mnt/cdrom/images/boot/img of=/dev/fd0 bs=1k. I guess I could have used pcmcia.img instead if had a PCMCIA CD-ROM drive attached to the Libretto.
Made a DOS boot disk for a partitioning tool From DOS, I used format /s a:, then I copied my partitioning tool to it, I used PQMAGICT.EXE.
Installed Windows 9x. When I powered up the Libretto for the first time I was offered the choice of installing Windows 95 or 98. I chose Windows 98 and let it install. For my method of installing Linux I needed an operating system that can retrieve the RedHat files into a filesystem on the Libretto.
Installed Network Adapter. I inserted a 3Com 589 and rebooted Windows 98. I set up TCP/IP networking and mapped a drive L: to the machine that contains the RedHat CD and extra files.
Copied RedHat CD. I created a folder c:\RedHat. Into this I copied L:\RedHat\Base, L:\RedHat\rpms and XFCom_Neomagic.rpm.
Shrank the W9x partition. I used Windows 98’s disk defragmenter to defrag drive C: and to try to move all the files up to one end of the partition. Then I booted my partitioning diskette and resized the W9x partition to below 1GB.
Used the RedHat 6 boot disk. I put the RedHat 6 boot floppy in the Libretto’s floppy drive and rebooted it. The RedHat install procedure started as usual. When asked Server, Workstation or Custom? I chose custom. If I chose Workstation it would lose my hibernation partition. I didn’t use Disk Druid, it doesn’t let you control the order of the partitions. I used FDISK. My partitioning scheme was
Dev Start End Blocks Type hda1 1 253 1020064 Win95 FAT32 hda2 254 258 1096704 Extended hda5 254 258 20128 Linux native hda6 259 490 935392 Linux native hda7 491 507 68512 Linux swap hda8 508 525 72544 Hibernation
Remember, I’d accidentally destroyed my hibernation partition in an earlier attempt at this so I just invented the details for hda8, I read that it needs to be the last 70 MB of the disk. I did some sums on the reported geometry of the disk and the size reported by the HD manufacturer. The 100CT has a 2,167 billion byte MK2105MAT drive with CHS=525/128/63 so that means just under 4 MB per cylinder. Note the CHS isnt real (the MK2105MAT has 2 disks and 4 heads). Its just reported this way by the IDE drive to fool the PC BIOS which can’t cope with cylinders over 1023.
I allocated mount points as follows
Mount Point Device MB /mnt/win hda1 996 /boot hda5 19 / hda6 913 hda7 66 hda8 70
I used Partition hda7 for swap.
Installed from HD. I told the RedHat installer to install from Hard Disk. The disk is hda1. The directory is . It installed all the RPMs for the packages I had chosen. This took about 20 minutes.
Removed floppy and rebooted. I had a working Linux system. I logged in as root.
Installed X-Windows driver. I made a directory /mnt/win and then did
mount /dev/hda1 /mnt/winI installed the NeoMagic driver using command
rpm -i /mnt/win/XFCom_neomagic*rpm.
cd to /etc/X11and
ln -s ../../usr/X11R6/bin/XFCom_Neomagic* X(Note: this driver is no longer needed with RedHat 6.2)
cp XF86Config.libretto100ct XF86ConfigThis wiped my non-US settings, In order to get my national keyboard layout correctly understood by xterms I had to edit XF86Config to reinstate the following …
Section "keyboard" Protocol "Standard" AutoRepeat 500 5 XkbKeycodes "xfree86" XkbTypes "default" XkbCompat "default" XkbSymbols "us(pc101)" XkbGeometry "pc" XkbRules "xfree86" XkbModel "pc101" XkbLayout "gb" EndSection
See Quentin Stafford-Fraser’s page for more ideas on configuring X to get the best out of internal and external displays.
Configured Networking. I told Linuxconf about eth0 and 3c589_cs. Painless.
Made KeyPad keys work. Xin Feng’s page on the Libretto 100 keyboard shows that the Fn key has some undocumented features. Use Fn to emulate the missing keypad
Fn + 7 8 9 0 is 7 8 9 * U I O P 4 5 6 - J K L ; 1 2 3 + M , . / 0 . /
Fn+F10 toggles the cursor-movement keypad overlay
Fn+F11 toggles the numeric keypad overlay.
XFree86 will switch video modes using Ctrl+Alt+Fn+P (if your XF86Config contains a Screen/Display/Modes line that lists several resolutions).
- Make the Floppy Drive work and build a rescue floppy.
- Nuke Windows 98. I could use Linux FDISK to change hda1 to “Linux native” and then format it and use it for Linux. If I do this I’ll need to find another way to reinstate Linux in the unlikely event it ever dies unrecoverably.
- Fix the APM daemon. The APM daemon handles power management fine however it always starts bleating that power is running out when the battery gets to 50% and it keeps bleating every few seconds. Currently I just kill it and restart it with no parameters. It doesnt seem to properly take notice of the parameters set in the startup file (must be a buglet). I’ll hunt down the startup file and play with the params to make it behave more quietly. (Note: this is no longer a problem with RedHat 6.2 and later)
Appendix 1: RedHat 6.1
I tried but never succeeded with RedHat 6.1. Using my previous method resulted in a bootable system but I could never get my network cards to work so I gave up on this. My advice is to use RedHat 6.2 instead.
Appendix 2: RedHat 6.2
Installing RedHat 6.2 was the easiest so far. I made a boot floppy from the pcmcia.img and was able to perform an NFS install over the network after putting the RedHat CD in another Linux PC and configuring NFS to export it to all users. I did have some teething problems with NFS but I forget the details - so be persistent, it works.
For X11, there is now no need to download and install the XFCOM Neomagic driver. I still used the XF86Config from that driver since the RedHat installer doesn’t grok the 800 x 480 display ratio. My XF86Config is below.
This time I swapped the original 2 GB disk for a 6.4 GB Toshiba MK6412MAT. These are the same physical dimensions. Its important to get a 2.5" HDD that is the same thickness (about 8mm). Some of the older Toshiba disk drives have the mounting holes in a different place so this is something to look out for. The mounting holes aren’t that important but they are used for attaching a handle used when extracting the drive. Again I reserved about 70 MB at the end for the Hibernation partition and gave the rest to Linux. The Libretto automatically recognises the HDD geometry - there is no need to go into the BIOS setup.
Appendix 3: RedHat 7.0
On 10/11/200 I installed RedHat Linux 7.0. My notes are as follows:
- Made a RH7 boot disk
- Copied RedHat directory from both RH CDs onto another Linux PC
- I couldn’t get it to install using NFS
- Installed anonymous ftp on the other Linux PC
- Booted floppy and selected upgrade
- Chose FTP source. Install continued OK.
- Installed bootloader to /dev/hda
Everything works fine, however, I don’t use the Libretto a lot these days. 32 Mb RAM is a little too small these days.
Appendix 4: RedHat 8.0
I had problems making a boot floppy and didn’t try very hard to overcome them. I Have Redhat 8.0 running on a desktops and servers but not on any laptops/notebook PCs yet. The battery has failed in the Libretto (3 years use, not bad).
I now have a Sharp Zaurus SL–5500 with a CF Ethernet card. This satisfies some of my needs for a portable Linux device. I haven’t yet got Ethereal running on it though.
Appendix 5: RedHat 9
I have tried numerous different ways to install RedHat 9. So far all of them have failed. My current plan is to order an adapter cable so I can install the 2.5“ IDE drive from the Libretto inside a desktop PC, do the install there using conventional CD and then replace the 2.5” disk in the Libretto and boot.
The adapter is needed as 2.5“ IDE drives have a different connector to the usual 3.5” (or older 5.25") IDE drives found in desktop PCs.
There’s some useful looking stuff on Mandrake 9 at P Nienhuis’s web page
Appendix 6: Soundcard
The Libretto 100Ct uses a Yamaha OPL3 SA3 sound chip that is compatible with the Soundblaster Pro.
Log in as root, run /usr/sbin/sndconfig. let it probe for a PnP card. It won’t find one and will ask you to choose. Select “Soundblaster Pro”. The settings are I/O=0x220, IRQ=5, DMA=0. You should get to hear a sample of Linus Torvalds and a brief bit of MIDI.
Appendix 7: Madge Token Ring Cards
At Madge’s website you can download the drivers for their Token Ring LAN Adapters. They currently (July 2000) have binaries for RedHat 6.1. For RedHat 6.2 you’ll need to recompile the sources. Change either
- scripts/configure: Around line line 635. “$DISTVER” = “6.1” to 6.2.
- install/main.c: Near line 110 change “newtSetSuspendCallback(suspend)” to “newtSetSuspendCallback(NULL, suspend)”. This doesn’t look right to me but the driver works this way.
Compile the source using “make” - ignore the numerous warnings. Then install using “make install”. Follow the instructions in the README file completely. Amend /etc/conf.modules, run depmod -a, amend /etc/pcmcia/config.
I had to eject and re-insert the PCMCIA card, because Linux had confused it with a memory card. Use “cardctl ident” to check that the PCMCIA device is reporting its name properly.
Appendix 8: XF86Config
Under RedHat 6.2 I use the normal XF86_SVGA driver. Here is a working /etc/X11/XF86Config for internal 800x480 LCD display. It needs more work to support all the internal and external display resolutions.
