Alternate install CD
The alternate install CD allows you to perform certain specialist installations of Ubuntu. It provides for the following situations:
- setting up automated deployments;
- upgrading from older installations without network access;
- LVM and/or RAID partitioning;
- installs on systems with less than about 384MiB of RAM (although note that low-memory systems may not be able to run a full desktop environment reasonably).
In the event that you encounter a bug using the alternate installer, please file a bug on the debian-installer package.
There are four images available, each for a different type of computer:
- PC (Intel x86) alternate install CD
- For almost all PCs. This includes most machines with Intel/AMD/etc type processors and almost all computers that run Microsoft Windows, as well as newer Apple Macintosh systems based on Intel processors. Choose this if you are at all unsure.
- 64-bit PC (AMD64) alternate install CD
- Choose this to take full advantage of computers based on the AMD64 or EM64T architecture (e.g., Athlon64, Opteron, EM64T Xeon, Core 2). If you have a non-64-bit processor made by AMD, or if you need full support for 32-bit code, use the Intel x86 images instead.
- 64-bit Mac (AMD64) alternate install CD
- Choose this to take full advantage of computers based on the AMD64 or EM64T architecture (e.g., Athlon64, Opteron, EM64T Xeon). If you have a non-64-bit processor made by AMD, or if you need full support for 32-bit code, use the Intel x86 images instead. This image is adjusted to work properly on Mac systems.
- Mac (PowerPC) and IBM-PPC (POWER5) alternate install CD
- For Apple Macintosh G3, G4, and G5 computers, including iBooks and PowerBooks as well as IBM OpenPower machines.
A full list of available files can be found below.
