This extract taken from: Deja News Search on Old for "ncr 3410 linux".
I've just finished installing Red Hat 6.0 on a microchannel architecture (MCA) based NCR Model 3410 (NCR Class 3355) PC using the BusLogic BT 646S SCSI adapter although any supported MCA SCSI adapter should work on your MCA system. This PC?s native video chip is the NCR 77c22 and is limited to 16 colors. The processor is a lowly 486/66 but it works OK. If you can find better supported video you will be happier if running ?X?. I didn't find any Red Hat 6.0 MCA boot disks so I created my own "imperfect one" on another Red Hat Linux 6.0 PC. The problem with the MCA boot disk is that it might not detect all the hardware you might have, it doesn't create the lilo.conf file and it doesn't run LILO to install your boot track. However, these steps can be done later after some messing around as you will see by reading further. The imperfect procedure below is one way how you can do the same to complete the Red Hat 6.0 installation for a SCSI based Microchannel system Hopefully, I didn't forget something major because I did this from memory after several attempts at the MCA installation.. This procedure requires that you first install Red Hat 6.0 on a non-microchannel PC. If this isn?t possible for you, perhaps you have a friend that is willing to install it on another PC. Preparation ======== 1. Read up on the HOWTOs for creating boot diskettes and creating linux kernels. You may want to purchase a good book on Linux also. 2. Write down exactly what hardware your MCA PC contains. You will need this when you define your microchannel kernel in later steps. 3. If using a SCSI disk, you may optionally (highly recommended) low level format your SCSI disk to make sure it will pick up the boot track correctly later. This will also reassign any bad tracks on the disk the you may not be aware of. 4. Create a second RedHat6.0 Install diskette. 5. Create a SlackWare Linux 2.0.x MCA boot kernel disk from http://www.dgmicro.com/mca/general-goods.html that will help fix the problems I mentioned above. 6. Create a SlackWare Linux 2.0.x color root disk from metalab.unc.edu (sunsite). Create a Red Hat 6.0 MCA Boot Diskette on another system ==================================================== 1. Install RH 6.0 on a non-microchannel PC using the diskette supplied by Red Hat. 2. After installation, run ?make menuconfig?, ?make config? or ?make xconfig? to define and save your default configuration to a alternate configuration named "orig.config." 3. Modify the configuration and create a very slim alternate microchannel configuration for just the hardware needed to complete the install. Include any SCSI disk controllers in your system but skip networking since it?s not absolutely necessary to complete the installation of Red Hat.. The configuration needs to be kept small so the compiled kernel file can be copied to a Red Hat installation diskette later in the process. You can add in the other hardware definitions on your MCA based system after the installation. 4. Save the config as an alternate configuration file named "mca.config" (or pick some other unique name here.) 5. Build a kernel using "make dep; make clean; make bzImage". 6. CD to /usr/src/linux/arch/i386/boot and run "rdev -R bzImage". 7. Mount a second copy of the Red Hat Installation diskette at /mnt/floppy using "mount /dev/fd0 /mnt/floppy" and then copy bzImage to /mnt/floppy/vmlinuz. Install Red Hat 6.0 on your MCA based system ================================== 1. Install Red Hat 6.0 on the MCA PC as you would any other PC. This installation may not detect all of your installed hardware but you can create a new kernel with all of the hardware later. 2. Insert the SlackWare 2.0.x MCA boot kernel disk while rebooting the PC. 3. Insert the SlackWare 2.0.x root disk when prompted. Press enter and login as root when ready. 4. Mount your PC's root partition by using "mount /dev/sda1 /mnt" (substitute the correct partition name if different. 5. Cd to /mnt/etc. 6. Create a minimal lilo.conf as follows substituting the correct partition in the root and boot statements: boot=/dev/sda1 prompt timeout=50 image=/vmlinuz root=/dev/sda1 label=latest read-only image=/linux root=/dev/sda1 label=linux read-only 7. Save the file as "lilo.conf" and exit vi. 8. CD to /mnt/lib/modules. 9. Delete all the compiled modules using "rm -rf *" or else you will have trouble booting Red Hat 6.0 later. 10. Insert the SlackWare 2.0.x boot kernel diskette while rebooting the PC. 11. Type "mount root=/dev/sda1" at the first prompt and press enter. This will boot your Red Hat 6.0 system with an older kernel from the SlackWare diskette. 12. Login using the root account and the password you entered during the Red Hat 6.0 installation. 13. Mount the Red Hat Installation diskette at /mnt/floppy using "mount /dev/fd0 /mnt/floppy". 14. Copy the kernel to the root of your system by typing ?cp /mnt/floppy/vmlinuz /? and pressing enter. This will place the compiled MCA kernel on your system. 15. Copy /mnt/floppy/vmlinuz to /linux. This will place a second copy of the compiled MCA kernel on your system. You can boot this alternate copy in an emergency. 16. Run LILO by typing "lilo" and pressing enter. This should map your boot track and install both copied of the kernel. You should see the displayed messages: adding latest * adding linux 17. Reboot you system and remove any diskettes. 18. Login to your newly installed system. 19. CD to /usr/src/linux and configure your kernel for all the hardware in your system, You can use ?make config?, ?make menuconfig? or ?make xconfig?. 20. Build your freshly defined kernel using "make dep; make clean; make bzlilo". 21. Install any modules by pressing "make modules; make modules_install" and pressing enter. 22. Reboot your newly installed microchannel based Red Hat 6.0 system. 23. Return to the non-MCA Red Hat system and run ?make config?, ?make menuconfig? or ?make xconfig? loading in the default configuration file named ?orig.config? so that you can now configure the non-MCA system with a non-MCA configuration. Good luck with your new Red Hat 6.0 PC(s). firstname.lastname@example.org wrote in message <email@example.com>... >Cokey de Percin
