I have an old 400mHz Dell with a 20G hard drive and 125M ram. Can I install and run CentOS on it? Thanks, Mike.

You can install/run the CentOS-3 OS. CentOS-4 might run. I do not think CentOS-5 would be able to be installed on the system.

CentOS 5 requires 512MB for installation due to building package dependancy trees. Once installed it will *run* with less, of course, package dependency issues can still arise afterwards. ;)

You need a combined(!) 768MB of RAM and Swap to successfully install CentOS 5.2 (see the release notes).

I have CentOS5 on a dell d400 latitude with 700MHz p3 and 256MB RAM.I installed using graphical installer and http for packages. Anaconda switches on swap real early but it all works. Switching out the hd for an ssd was a huge boost in performance and battery time.

I install many Xen domU systems with 256MB running CentOS 5.x. If you use text base installer, you should have no issues.

And really it is a performance question as long as you have 256M of real memory, the rest swap. Since I always make my swap > 2xRAM, I am always installing on a system with at least 768Mb combined.
I do not like the DIsk Druid default of putting the swap drive into the LVM partition. I always redo the partitions so that swap is its own partition.

Why is that? Old school habit or is there a real benefit?
Swap performance should be equally good whether it be raw disk, raw partition, LVM logical volume or even a flat file on today's kernels, but maybe there is something I am unaware of.

It just feels wrong in so many ways.
Why is /boot its own partition and not swap? I suspend to swap, so swap has to be as accessible as /boot?
Am I going to enlarge swap at some point using LVM tools? Or shrink it? Can you even do that with a swap partition in LVM? So what ARE the values of swap in LVM? One less partition, I would think if you are going duo boot. But if not, again, where is the beef?

Well the only reason /boot isn't possible in LVM is because grub can't of yet handle reading LVM volumes. As soon as it can though, there will be no need for a separate /boot.

You can enlarge or shrink it if you want, remove it from swap first, but many people just create another LV and add it to the mix.
I think the biggest benefit to swap on LVM is when working with software RAID1 on the main disks, where you don't need to worry about creating a special MD just for swap, md0 for /boot, md1 for LVM.
Not really a beef, in my books though it's added partitioning and potentially wasted space, but disks are big these days, so what.

Then we just need BIOS support to boot from LVM, and we can create the PV on /dev/sda and never care about the old partitions anymore. Everything should be in LVM for ease of management.

Oh boy! You've heard rumors that the BIOS manufacturers are going to begin supporting file-system-specific layouts? I find that hard to swallow.

Well, in theory we don't need BIOS support. The BIOS will check that the first sector of the device is signed with 55AAh and just jump into the code in the first sector. So if LVM leaves the first sector and track (so grub can hide there) alone, it should work just fine.

As I thought (remembered). Which means no additional BIOS support is needed. What's needed is that the first sector understands LVM (or whatever the file system is if there's not LVM). So if we put the root onto a "conventional" file system, the first sector would be the boot code - no GRUB/LILO or anything else needed (IIRC). Of course, then no parameters passed, no selection of alternate boots, etc.
Just like the old days! :-)
Simplicity has its strengths and weaknesses.

The downside of file system swap is when you reboot a machine with a large amount of swap on the file system it can take forever to get past the swap checking.

That's certainly the problem, thanks. I don't use swap on VMs, for fairly obvious reasons.
I guess I could use file-based swap, so it's easy to turn off and recover the space after the install finishes. My VMs really don't need more than 512 MB of RAM when running.

I have one box running CentOS 5.2 with 384 MB of RAM. I did the graphical install on it, as on the 2 boxes with 512 MB of RAM.
You can install 5 on it, but you probably won't be too happy with it. Make sure to have more than the default amount of swap installed.

Just to comment that this was with an actual RH installation DVD, not CentOS. The only systems I've installed CentOS on has had at least 1GB of RAM.

Bring the memory up to 256Mb.
I have a number of test servers running on similar platforms. But you have to get the memory up to at least 256Mb...

It depends. If you have all 256Mb, it still works. But if your video 'steals' some of it, yes you go to text install...

My firewall is a Pentium 75 with 48 MB of RAM running CentOS 4.7 + current. I did a text based install, and the install took a very long time, but it works very well ..despite taking about 5 minutes to boot up.

I remember running a color NeXTstation with 24MB in 1994 and it ran smoothly and I had Wordperfect and Lotus Improv running.
Now if I could only have an OS from back then running on today's hardware.

--- Yes, even with a HP Machine 400Mhz Celeron and 128 MB of ram will work wonders. Top it off running on the GUI, all a bit slow but it will steam along. Try to find 3 more MB of ram because you really need it. Firefox is a lag to load but will eventually get rolling.

Depends on what you want to use it for. I have successfully run CentOS on PIIIs with as little as 256MB of memory, but with limited functionality enabled, usually as a firewall, SAMBA server and/or web server. In all cases I took care during installation to install as little software as possible, disable all unnecessary daemons and use only the command line.
