Why Solaris? Th fioricet cod s is actually a good question. Why use Solaris, when you can have Linux? Solaris is a commercial system, the hardware support is scarce. But if you are reading this you have probably already decided on fioricet cod using Solaris. If not, here are some reasons: · I have a part-time job administrating Solaris machines. It is of no use that I learning all the neat command parameters and nifty Linux tricks at h fioricet cod me, when I can't use them on my Solaris-Box. · Sun was giving away Solaris for what they call ``Shipping and handling cost only'' for some time. They might do that again. And almost-free-of-charg fioricet cod is always a good deal. · Another reason might be that you like CDE. 1.2. Things covered in this HOWTO This HOWTO tries to help you install Solaris 7 or 8 on an x86 computer already running Linux. Th fioricet cod main targets are · not to destroy any data, see section ``Preparing your Harddrive'' · To make Linux and Solaris coexist (boot manager), see section ``Boot-Managing'' · To share data between Lin fioricet cod x and Solaris, as described in section ``Sharing Data'' 1.3. Referenced versions The reference versions used while creating this document where: · Solaris 7 x86 (= Solaris 2.7 / SunOS 5.7) · Sol fioricet cod ris 8 x86 (= Solaris 2.8 / SunOS 5.8) · Linux 2.2.14, 2.3.99-pre3 · fdisk v2.10f The information might apply to other versions of the software, or it might all be different. 1.4. Warning Ple fioricet cod se back up any data before messing with your system! A lot of the things described in this document may result in excessive data loss! I am not responsible for any data loss! See also section ``Legal s fioricet cod uff'' 2. Preparing your Hard Drive To Prepare your hard-drive for Solaris, you need to know about standard PC partition tables and about Solaris disk slices. In this HOWTO I talk about single-disk sys fioricet cod ems only, but all the information should also apply to a multi-disk environment. 2.1. Traditional PC partitions The standard partition-table has only 4 entries. The entries important for us are the fo fioricet cod lowing: A Primary Partition Takes up one entry, and contains exactly one partition. A waste of resources, but the only partition you can boot from! An extended Partition Takes fioricet cod p one entry, but can contain multiple DOS, Linux, and other partitions A Solaris Partition Takes up one entry, but can contain multiple Solaris Partitions To find out what partitions are fioricet cod present on your system, use the fdisk program. Partitions numbers 1 to 4 (hda1..4, sda1..4, ...) are the ones in your partition table. 2.2. Solaris partition labels Solaris has its own partitioning sc fioricet cod eme. It uses one entry in the partition table, and this entry is and acts as this partition would be the entire disk. This virtual disk is then divided in up to 8 slices. The third slice, s2, covers th fioricet cod whole virtual disk, so you actually have up to 7 slices for Solaris. Unfortunately, the Solaris partition entry has the same type as a Linux Swap partition (82). Therefore, you should not have any Linu fioricet cod swap partitions as primary partitions. Linux doesn't care about this, but who knows what Solaris does? Although the Linux fdisk program has some ``Sun disklabel'' support, this doesn't seem to help an fioricet cod . 2.3. Hard disk space Of course, Solaris needs disk space. The minimum installation of Solaris 8 is about 300 MB. For the normal tools its about 700 MB, and for a ``developer-system'' about 1 GB. Bu fioricet cod this is only the space required for the base installation. You might want to add a lot of GNU-Tools, and other stuff. And if you want to share data between Solaris and Linux, this has to happen on the fioricet cod olaris partitions. You might even think of sharing your home directories between Solaris and Linux. As the time of this writing: Forget it! I messed up my home directory doing so and I was very happy ab fioricet cod ut my backup. See also section ``sharing data'' 2.4. Quick check list Here's the quick check list. Make sure you: · have used no more than 3 entries in your partition table · have no Linux swap par fioricet cod itions as primary partitions · Have at least 1 Linux ext2 partition as primary · Have at least 1 GB unpartitioned space 3. Preparing Linux 3.1. Building a new kernel Some people donīt like buildin fioricet cod a custom kernel. For those of you: you must build your own kernel if you want to share data between Solaris and Linux on one hard disk. If, however, you do not want to share data, you are safe with you fioricet cod old kernel. Here are your kernel options for ``Solaris compatibility'': · Under code maturity: Prompt for development drivers Unfortunately UFS writing is still experimental. · In file sys fioricet cod ems: UFS file system support UFS is the Solaris file system UFS file system write support" The only way to pass data to Solaris partition types / Solaris (x86) partition ta fioricet cod le support" Is needed for the slices within your Solaris partition to be found. Additional info about kernel building can be found in the Kernel- HOWTO 3.2. Preparing your boot loader Bef fioricet cod re messing with your boot loader, please make sure that you have an emergency disk ready which enables you to boot your old system. Unfortunately the Solaris install overwrites the master boot record (M fioricet cod R) and overwrites your old boot manager. Fortunately, the Solaris boot manager is able to chain-boot. For this to work you have to put your old boot loader (e.g. lilo) into the boot sector of one primar fioricet cod Linux partition. For lilo this means: look at your /etc/lilo.conf. Look for the boot= line. If it is something like boot=/dev/hda1 everything is fine. But if itīs something like boot=/dev/hda it points fioricet cod to the MBR. Please change it to point to a primary Linux partition (e.g. boot=/dev/hda1) A way to check if your boot-loader is chain-loadable is installing lilo in to the MBR and trying to chain load yo fioricet cod r other boot-manager. I used the following file called lilo.conf.mbr for this: ______________________________________________________________________ #lilo.conf.mbr #Lilo in Master Boot Record doing no fioricet cod hing but chain-loading another lilo boot=/dev/hda root=/dev/hda5 install=/boot/boot.b map=/boot/map vga=ask delay=50 other=/dev/hda1 label=lilochain _______________________________________________ fioricet cod ______________________ You can then run lilo -C lilo.conf.mbr to install lilo into your MBR. And donīt forget to run lilo to have lilo in the boot sector of your hard-drive. If you reboot now, you shou fioricet cod d have a lilo-prompt. When you select other this chain loads the old lilo, which in turn loads Linux. 4. Installing Solaris 4.1. Solaris interactive Solaris 7 Solaris Interactive is on the fioricet cod irst CD. Boot it, select Solaris interactive Solaris 8 On the Solaris 8 CDs the interactive installer is on the first software CD. You don't need the install CD at all. The Solari fioricet cod installation itself is quite straight forward. One thing that might be confusing is the partitioning. Solaris will automati cally use all the free space on your hard disk, and create it's own virtual fioricet cod isk in it. And when it comes to slicing up your virtual disk, donīt forget to add space for Solaris/Linux exchange. A good place for this is an extra /export/share partition. Please Note: If you abort d fioricet cod ring the Solaris installation, the MBR of your hard disk may already be overwritten and you may not be able to boot from the hard disk at all. 4.2. Web-Start I couldn't get Web-Start to work at all. P fioricet cod ease mail me if you have any experience using it. However, once Solaris was installed, I had no problems adding web- start-packages 4.3. Getting GNU-tools Solaris standard installation doesn't even h fioricet cod ve a less command. Some people recommend getting the Redhat Package Manager (RPM) for Solaris, but the standard packaging tool will usually do it. You can find many nice packages at http://www.sunfreewa fioricet cod e.com The standard packages can be used with pkgadd , and the web-start packages with java 5. Boot managing 5.1. Using the Solaris boot manager When booting, fioricet cod he Solaris boot manager gives you all 4 primary partitions for choosing which to boot from. If you had your boot loader installed on the boot sector of a primary partition, everything should be fine. Ju fioricet cod t boot from this partition, and Linux should come up. 5.2. Using lilo Now you have lilo as a secondary boot loader, but you want it to be your primary boot loader again? No Problem. Lilo can easily ch fioricet cod in boot Solaris. Just add the appropriate other= lines to your lilo.conf For testing, you should add the Solaris chain loading to the lilo in your boot sector first. Then try chain loading lilo, Solaris fioricet cod lilo, Solaris, ... until you have enough of it. If this works, you should be able to put lilo back into the MBR again. However, Solaris might have messed up your partition table. This has happened on my system after installation of Solaris 8. Lilo doesn't like the new partition, nor does fdisk. I had no problems with Solaris 7 5.3. Using grub Unfortunately, I have no experience with grub booting Solaris. If you do, please mail me! 6. Sharing data 6.1. Using a shared partition If you have build your kernel with Sun disk label support and UFS support as mentioned in section ``building your new kernel'', you are now able to mount your Solaris partitions. During boot up, you should get something similar to: hda: [PTBL] [523/255/63] hda1 hda2 < hda5 hda6 hda7 hda8 > hda3 M
