In the same vein, I am impressed by what David Plater did with a 486 and 8 mega bytes of RAM, see here.

Hi,

You could do a network install as long as the network device is available for Ethernet or wireless. Problem would still be the boot for the resident hardware. Sure you could do the install from another machine but still some tweaking would be necessary once the HDD was moved to the older hardware.

Doable, yet I see no reason other than the challenge & learning experience. I still use older IBM 780el Laptops as controllers but keep the machine OS the same as when first moved to Slackware. A few have been upgraded to 12.1 but retained the original version on the drive partition(s).

8Meg is still doable.

To run the installer in that little memory, unpack initrd.img and use it as a conventional root partition on a spare partition rather than loading it into a ramdisk.

The kernel needs scything and udev needs calming down but it's certainly still doable.

It's also very possible to still fit a useful kernel onto a 1.44meg floppy, start with 'make allnoconfig' and build up only what you need.

By comparison CentOS/RHEL requires 768MiB for the Anaconda GUI installer and 512MiB, I believe, for the text-based installer. I'm not faulting Red Hat here just making a comparison.

If initrd.img from Slackware 14 RC4 is in .., then
Code:
gzip -dc ../initrd.img | cpio -i -d -H newc --no-absolute-filenames | xargs du -sh
returns 53M

And that's two full sets of kernel modules, firmware and of course the installer itself!

Only the modules needed for installation, though...

Just finished the upgrade from 13.37 to RC4 on a Pentium P133 with 80MB memory.

After the upgrade midori stopped working, complaining about the lack of libnotify.so.1, symlinked it to libnotify.so.4 and it works again. Relieved not to have to rebuild webkitgtk again, it took 6 days and nights - 144 hours to compile!

Hmmm.... almost forget that my own 'old' laptop does not like the gl xscreensavers ---> black screens that require reboot . Recompiled and upgraded the xscreensaver package and used --without-gl. Lost all the cool screensavers but system now stable . Come on release version!
