Should this work?
Before The InstallationQ: How can I use my old hard drive with OS4? I have a lot of important data stored on it, using "XYZ" filesystem.
A: OS4 supports (out of the box) FastFileSystem and SmartFileSystem. If your XYZ is neither of these, you can still read/write to the partitions using XYZ if XYZ is stored in the RDB of the drive. Use Media Toolbox or HDToolbox to find out what is stored on the drive. Then XYZ filesystem has to work emulated under OS4 PPC (some may try to burrow into the old 68k OS).
For further details on Filesystems and the RDB, read the Media Toolbox documentation.
Q: Can I just over-write my old OS1/2/3 system partition with OS4?
A: Not quite, the partition has to support the "Long Filenames" feature of FFS2. This means setting the partition type to "DOS\7", rather than the "DOS\1" or DOS\3" that it is now. You can do this either of two ways:
Q: What do "DOS\1", "DOS\3" etc mean?
A: They are shorthand to describe the way a disk partition is formatted. The 4-byte word contains the three letters in ASCII and a single binary byte for the type, eg "DOS\3" = 0x44, 0x4F, 0x53, 0x03.
Q: How can I be sure of my IDE chain?
A: The IDE devices in your AmigaOne may require some careful connections to ensure proper operation. If you are having trouble with some (but not all) drives, and you are sure the Master/Slave jumpers are set correctly, check these points:
During the InstallationQ: I can't boot the CD. It just says "Bad Magic Number".
A: You are using the wrong U-Boot command. This is not a Linux CD. Try "boota".
Q: I can't boot the CD. It just says "** No disk inserted in drive 0 **"
A: Make sure that your boot device is the CD or at least that the CD is the first bootable device it finds. Type "menu", then interrupt the countdown with the space key and select "Boot Sequence" from the list. Now make sure that "Boot Device 1" says IDE CDROM. You can have "Floppy" for device 1 and "IDE CDROM" for device 2, if there is no floppy disk in the floppy drive, otherwise U-Boot will try to boot from the floppy first.
Q: I can't boot the CD - I've checked the boot device and "Boot Device 1" is set to "cdrom". But when I enter "boota", U-Boot just returns with a prompt. What's wrong?
A: Are you sure that you have the correct U-Boot firmware installed in your machine? Type "ver" at the U-Boot prompt to check. To match the pre-release, it should say "U-Boot 1.0.0 (Apr 12 2004)".
Q: I put the Install CD in the drive, checked that "Boot Device 1" is set to "cdrom" and typed "boota", but nothing happened. U-Boot just returned with a prompt. What is wrong now?
A: U-Boot is not smart enough to detect a new CD in the drive. Type "ide reset" to make U-Boot recheck the drives, then try again.
After the InstallationQ: The installation went OK, but the installed system won't boot when I take out the CD. When I type "boota", U-Boot says "Second level bootloader is too old; please upgrade it".
A: The version of slb that is installed in the RDB of the boot disk is too old for the version of U-Boot that you are using. See the answer to the next question.
Q: The installation went OK, but the installed system won't boot when I take out the CD. When I type "boota", U-Boot just returns with a prompt. What could be wrong?
A: U-Boot can't find the "Second-level booter" on your hard disk.
A: "SLB" stands for the Second Level Booter that is stored in the RDB of the system boot disk. There is no equivalent in the Classic 68k system. SLB finds the Kickstart directory and starts the loading process.
Q: When I finish the install and reboot, I can't see the display. It all appears wonky/shimmery/unreadable/ does not appear at all. What did I do wrong?
A: Probably you chose an unsuitable screenmode. Some graphics cards and TFT screens are particularly critical. You will have to repeat the installation, but this time select a different screenmode at the end of the procedure. Did you try the "Default" mode? If you have problems, try that first, you can always change it later in the running system.
Q: I've got it to boot the installed system, but I can't get a high resolution screenmode. What can I do?
A: In the Devs: drawer are some Picasso96 settings files - "Picasso96Settings-Radeon" and "Picasso96Settings-Voodoo". You can copy some or all of the modes from these files to your active "Picasso96Settings" file, using Sys:Prefs/Picasso96Mode. Read the documentation for Picasso96Mode first.
Should this work?Q: My USB mouse does not work. Why?
A: USB is still experimental and has not been distributed in the pre-release.
Q: What about my printer: can I use it?
A: Printer support is still experimental and has not been distributed in the pre-release.
Q: What about my dial-up modem: can I use it?
A: The serial port is not available for general use in the pre-release.
Q: Why does the serial port not work?
A: It works well, but currently (in the pre-release) it is reserved for diagnostics and debug messages.
Q: Why can't debug messages (or my modem) use the second serial port?
A: It's not yet supported by U-Boot.
Q: I was playing with the menu in U-Boot and now my A1 does not boot any more.
A: When you enter the "Boot Select" menu by pressing Enter during the menu countdown, U-Boot clears the variables "boot2" and "boot3" and sets "boot1" to "floppy".
There are two ways of fixing this:
A: The best place for "eth3com.device" is where it is distributed - in "Devs:Networks". If a "device" is in that drawer, it can be referenced directly in a Roadshow script without needing a path. If you move the "device" into "Devs:", you will have to add the path in the script, eg "Devs:
