AmigaOS 4.0 - Installation

The Initial OS 4.0 Installation Pack

When you receive AmigaOS 4.0, what you get is a nice cardboard folder printed in bright orange, clearly labelled Developer Pre-Release as you can see from the picture on the left, and that is it. Nothing else. Everything you need is on the CD so you must have a working machine of some type in order to get started.

On the back of the cardboard folder you will wee that there is a small white sticker with your OS4.0 license number printed on it, in the format XXXXXXXXXX-XXXXXXXXXX-XXXXXXXXX, where X is an alpha-numeric value. In order to obtain further updates, you must create yourself a login to the Hyperion website and register your license.

Inside there is the OS4.0 CD and some brief Installation Instructions:

Installation Instructions

In order to install AmigaOS 4.0, your AmigaOne needs to be flashed with the latest firmware. You can find this firmware on the CD in the "Firmware"directory. You need to select the appropriate update (either "from_0.1" if you have U-Boot 0.1, or "from_1.0" if you have a beta U-Boot 1.0; use the 'ver' command on the U-Boot prompt to find the version number).

After the firmware upgrade, you can boot this CD. From the U-Boot prompt, enter

> ide reset
> setenv bootl cdrom
> boota

If you have any trouble installing AmigaOS 4.0, you will find an extensive installation guide on the CD in the directory "OSInstallGuide" on this CD."

That's it. Wasn't that simple. Well, with hindsight, not really......

We seriously suggest that you print the OSInstallGuide BEFORE you attempt any part of the installation, or copy the files to another PC and refer to that during the installation process, or preferably both. The reason for the latter is that while the hard copy has a number of useful pictures, they are rather small and difficult to read. If you click on the images using your browser an enlarged image is displayed which is full size and much easier to read.

Section 1. Updating your Firmware
As it states in the Installation Instructions above, the first step is to update the Firmware.

However, before you can do this you will need to use another computer to burn the appropriate ISO image of the file from the "Firmware" directory first. You could try creating a bootable floppy using RawWrite but we kept getting checksum errors, so we decided to burn the CD instead, which incidentally worked first time. Further information about updating the firmware is available here.

If you are not sure how to do this, check your CD burning software for an "ISO" option - in the version of Nero we used it was buried in the "other" category; later versions of Nero have it under "Copy & Backup".

Section 2. Configuring U-Boot Parameters
Here it is simply a matter of following the instructions - this is where the browser version was most useful being able to enlarge the pictures to read the parameter values, except that some of the instructions have changed since it was released. In summary these values are:

    On the Integrated Peripherals Menu:
    • For PAR Port Mode, it states this should be 'ECP' whereas it should be EPP
    On the Boot Sequence Menu (for U-Boot 1.1.1 prior to 05-Mar-2005):
    • Boot Device 1 should be set to IDE Disk
    • Boot Device 2 should be set to IDE CDROM
    • Boot Device 3 should be set to Floppy
    On the Boot Sequence Menu (for U-Boot 1.1.1 after 05-Mar-2005):
    • Boot Method should be set to Amiga Multiboot
    • In Amiga Multiboot Options:
      • Boot Device 1 should be set to Onboard VIA IDE Disk
      • Boot Device 2 should be set to Onboard VIA IDE CDROM
      • Boot Device 3 should be set to Floppy
    On the PCI/AGP Menu:
    • For PCI Interrupt A, 'IRQ Level' should be set to IRQ   9 with 'Trigger by' set to Level
    • For PCI Interrupt B, 'IRQ Level' should be set to IRQ 10 with 'Trigger by' set to Level
    • For PCI Interrupt C, 'IRQ Level' should be set to IRQ 11 with 'Trigger by' set to Level
    • For PCI Interrupt D, 'IRQ Level' should be set to IRQ   7 with 'Trigger by' set to Level
If you require further instructions on how to change these values see U-Boot Boot Preferences Menus.

Section 3. Installation CD
This involves loading the CD and typing the information supplied. If you are not familiar with the U-Boot parameters, the "setenv boot1 cdrom" statement sets the first boot device to "cdrom", so "boot1" should be read as "boot one" not "boot ell".

Section 4. Locale Preferences / Input Preferences
While this may seem like useful stuff, it's really only important if you want to use a language other than English. If English is your choice, simply click on "Proceed" or "Use" and don't bother setting values at this time. That can all be done later.

Section 5. OS4 Installer
This covers the initial screens displayed by the Installer - simply follow the instructions.

Section 6. Configuring Your Hard Drive
This covers setting up the DH0: and DH1: partitions for OS 4.0 - simply follow the instructions.

Section 7. Installation
This is where you eventually get to install OS4.0. After the reboot, the Locale Preferences / Input Preferences screens are repeated and can just be ignored for English. Otherwise, simply follow the instructions.

Section 8. Booting to OS4
When you get here you have finished the initial installation and hopefully OS4 will boot by itself.

The next step is to copy the remaining files from the AmigaOS 4.0 Installation CD. The first of these is 'Contrib', which is a drawer containing a number of other drawers containing useful software developed by third parties, and you can simply drag this across to your System disk, or wherever you want to put it. The second is a drawer called 'IBrowse2.3' the contents of which need to be installed, so we suggest you first copy this to the 'Contrib' drawer created above, and then click on the 'Install-IBrowse' icon within it to install it somewhere - we suggest 'Utilities'. Finally, if you intend to do any program development you will probably need the third drawer called 'SDK', that you can copy wherever you wish.

Section 9. Oh no! It didn't work
As with any installation process, there can always be variables that haven't been allowed for that can cause things to go wrong.

In Section 3, the instructions say:

"Once the kernel (kickstart) has loaded, your screen will go blank and your monitor may go
onto standby. The CD drive is still being accessed at this point, after about one minute
you will be presented with a welcome message on a White background"

From our experiences they were partly correct, in that the screen went blank alright, and the lights on the keyboard flashed, but that was it. Nothing! In despair we repeated the previous steps to no avail. A quick search on the Internet revealed others had hit this problem too, and for many the solution was a different video card, someone had waited all night without success, while another found the solution was as simple as pressing Ctrl and the two Windows keys (same as Ctrl-A-A), so we tried that too, in vain. Our video card was an ATI Radeon 7500 LE from PowerColor, so we tried using a Radeon 7000 card from Game Accelerator. Still nothing until we tried the Ctrl-Win-Win technique - the keyboard lights flashed again, and within seconds there was OS4 on the screen. Success at last!

Subsequent to this another member with an ATI Radeon 7000 card has experienced a different problem at the same place, except the screen was all wavey with jagged lines down each side and showed the Amiga Insert disk screen - after much trial and error this was traced to a problem CDROM drive, which although it was used to install Debian and OS4 can now read files using it, it would not work during the OS4 install.

Pre-Release AmigaOS 4.0 Update 4 Installation

While updates 1, 2 and 3 required AmigaOS 4.0 to already be installed, update 4 could be installed to a new system or used to update an existing system. It should be noted that any issues we identified above have long been resolved, so as long as you follow the instructions in the accompanying PDF file everything should go according to plan, and even if it doesn't the PDF file should help you determine what is wrong and how to rectify it, although the delay discussed above seems to take even longer on some systems, so please be patient even if you don't see the disk light flashing.

AmigaOS 4.0 Final Installation

The OS 4.0 Final Update is a complete re-install and will overwrite any existing system so make sure that you take a backup of your existing system first or that you install to a new partition. Some of the issues encountered during previous updates may still be encountered such as ADSL setting where only a modem is used - the install assumes that a router is being used. Swedish users may also have a slight problem but there is a simple fix for that. And if you're expecting to find a Tools directory you won't because the contents have been split between System and Utilities.

The re-install takes about an hour, and then you spend the next few hours or more reinstalling the additional software, some of which need to be updated from OS4depot, and sorting out why tings don't work as before. While most programs seem to work some do not, such as Final Writer, VistaPro 3, etc. Others that you would expect to work, having been written for OS4, and some of the 68K programs, require the 'ADDCHIPRAM=x' parameter to be added to the SETPATCH command in the Startup-Sequence.
