What's The Fastest Loading OS For x86?
core10k asks: "I have a question concerning quick loading operating systems. I have a laptop that I use which I'd *like* to have running in the 10 seconds or so it takes for the BIOS to heat up, but then I have to wait for Windows 98 to load. And I know that Linux is even slower loading up. So I was wondering, does anyone know of a fast-loading operating system that has a half-decent (not necessarily great) C/C++ and GUI toolkit?"
You may need to set it up first, the laptop's manual should explain it. But you'll probably need a FAT partition (as the first partition on your drive) to store the file. And the file will be the same size as your RAM (i.e. a 64MB file for 64MB RAM). When you turn your laptop on, this file will be read into RAM by the BIOS. It takes 10-20 seconds. Try turning off the power to your laptop and see what happens. On mine (a Compaq), pressing the power switch (instead of shutting down) suspends to disk automatically.
I don't agree that windows is faster to boot than Linux at all. This is true when you are talking about a brand spanking new win95 installation and only considering 'time to GUI'. This isn't the whole picture however... As any Linux user will tell you when you see the X login prompt the OS is finished loading, likewise when you login your window manager starts and away you go. IMHO Windows 'pretends' to load when this isn't the case. I use NT in the office (smb server by my illegal linux box :) ) and I can promise you that when the NT login prompt appears on my screen (Which, incidently takes about four times as long as the X prompt) there is no way on earth that I can actually login for at least another minute as the hdd churns away. Likewise once I have logged in the windows GUI appears but I can't actually do anything until the hdd stops doing 'stuff'. Add to this the fact that trying to do things ONCE THE GUI IS UP but BEFORE THE HDD HAS STOPPED can crash the system this becomes another clear case of 'The winner in... Linux.'. Dan

BeOS is indeed nice, but a minimum version of the linux system is even faster - the main bottleneck being time to mount the ext2 partition. ReiserFS mounts much faster, so Linux with ReiserFS booting into 'linux single' is the fastest I can think of. BeOS is the fastest booting complete environment.
Who said you have to wait for everything to load before starting a shell? why not modify the inittab and rc scripts and whatnot to run a shell on the first VC as soon as all the manditory services and drivers are load, things like SCSI, /usr, etc. Sure, the first minute or two ill be slow while you load sendmail and apache and all the rest of the stuff manditory for a personal computer, but you will have a shell. I'm sure it wouldn't be too hard to do that same with X, for nice GUI in the first few seconds.

There must be something wrong. I timed my Windows 2000 boot last night. It was about 65 seconds to boot on my P2-300 with 64MB/ram. I timed from the moment the video card initialized until I had a login screen and the disk stopped going crazy.
It might be worth your while to go to ftp.lineo.com/pub/drdos and try a copy of their fine product. It does it's own "DOS Extend"ing, and can task-switch or multitask (although the implementation isn't as smooth as, say, Linux). It's much cooler than MS-DOS in many respects. If I had to use DOS, I'd pick up a license for it in a heartbeat. Of course, you don't need a license to "evaluate" it for 90 days, if I remember correctly.
I was able to load BEOS on an AMD K5 32mb.
...
Only problem was Beos didn't support the K-5 so it would run until I started a program then...KABOOM!
The Linux BIOS Project was in this /. article just a week ago. It's not ready for prime time yet, but does all the BIOS step in about 0.1 seconds! Combine this with the right Linux distribution (debian has a fast (binary) service startup program - do others?), and a carful choice of which services you run, and Linux would boot REALLY fast! :)
And is vunerable to many virii.
But it does boot fast.
okay, i just timed it down to the second. Windows 2000 took 2 min and 14.5 seconds to boot from video card init to login prompt.
;-}
Linux took 1 min and 22.7 seconds from init to prompt.
I really don't know why windows takes so long to load.. oh well, since i'm in linux most (99.9%) of the time anyways, its not too much of a problem. but i do wonder why.. i may look under the hood and tweak it a bit.
I don't know about linux taking longer then windows. Usually it takes less then a miniute and a half for my computer to go through the bios, pause for 5 seconds while lilo gives a chance to choose windows or linux, then load the kernel, modules, start services, etc. to a login prompt (Redhat 6.2).
It's much faster then the 5 mins it takes for windows (2000 Professional)
I have an AMD k6-2 350 with 64M RAM. not bad, IMHO.
I've been amazed by it's speed. 9 seconds to boot, another three to mount both my other drives with FAT32 [REALLY FAT32 ;-)] filesystems. And app development is a dream - an entirely C++ oriented framework, of the app/view/data variety.
And it's free. www.be.com

While this really isn't a solution to your problem, Linux is definitely not slower loading than Windows. If you were to run the same functionality (daemons and such) on Linux as a basic Windows machine, Linux loads MUCH faster. Even with a bunch of daemons set to load, Linux loads as fast as a Windows machine that's not doing anything networking.

QNX is closed-source, and mainly aimed at real-time tasks. I tested the boot disk too. It includes a nice small graphics demo. I managed to get fifteen instances of the demo running at once, but starting up one more just caused the system to freeze. I had to reboot, and never tried QNX again.. :)
By the way, I saw the full version of QNX 4.54 pass by in alt.binaries.warez.ibm-pc.os a few months ago. Probably some people are just collecting OS'es..
like do you really need sendmail running in the background of you personal box
A lot of people do need sendmail (or, rather, an SMTP daemon of some sort) running, for fetchmail (and/or getting mail directly to your machine).
QNX is supposed to be giving away the full version for non-commercial use. But so far seems to be a lot more hype than anything else. The offer started months ago at http://get.qnx.com but so far they've yet to release it.
My other first post is car post.
When we installed Linux (Red Hat 5.2 deluxe) for class in college, we clicked "Everything" for services to start at boot-time, and the boot-time wasn't noticeably longer than Win95 (although it wasn't booting to X.)
So if you turn off most everything (sendmail, named, finger, etc.), it should boot pretty quickly, and be a lot more secure.

LOL! Now let's see a development environment on it.
WinCE still sucks pretty bad. I test devices running CE, and it has plenty of memory leaks here and there. And you know how well a typical piece of M$ software handles out of memory conditions... hehe

Suspending to disk would solve this problem, if you're laptop supports it. Most newer laptops do.
I received a 1.44 mb floppy from a friend labeled "qnx realtime operating system demo (modem version)". He said it was bootable on x86 and I was curious, so I decided to give it a go.
It turned out to contain a contain an OS complete with windowing system and internet browser. Admittedly it didn't work first time, and I had to modify a couple of BIOS settings that it didn't like, but I was really impressed once I got it going. The windowing system took about twenty seconds to appear from the time the BIOS started the floppy going. It created a file system in RAM, and I was able to dial an ISP and surf. Some forms didn't work, and Java support is dubious, but you can't expect that much from something packed onto a 1.44 mb floppy.
The website has a boot floppy image which you can download. The latest version claims to allow additional driver and application installion via the network. Apparently they are downloaded (into the ram disk? - I'm not sure about hard disk support at this stage) and installed on the fly.
This OS looks cool, and would totally rock with a hard disk , as it would boot in about four seconds. I suppose having a hard disk would lead to complicated boot routines that loaded permenantly stored drivers and other processes though, so that argument might not hold up . . . .
Ok Ok, it would suck for many applications, and is mainly targeted at developers at this stage , but all you hard core "thin client, server based" computing enthusiasts should check it out if you haven't already heard of it.
Check out an old version of slackware or maybe debian. RedHat is great and all but if you are looking for boot time rather than ease of configurability, etc. then it is terrible.
Also thought I would mention that it is an install of less than 100 MB, try doing that easily in RedHat.

Get to know your linux box. Mainstream distros are geared for everybody and do a lota stuff you probably don't give a damn about.
One other thing. Really large hard drives take forever to mount. look around there are ways to speed this up like reducing redundant fs checking (may not be a smart thing to do)

BeOS...10 seconds or less on my 450 mhz 192 MB boxen.
But isn't the purpose of the Doomsday machine lost if you keep it a secret!
Free for personal use, and all the way up in under twenty seconds(power switch to finish). I'm using it as a 'instant boot' client on a couple of 486-33/24M laptops I had lying around..
Very, very nice..
BeOS is also quite quick. I'd expect it to come in under thirty on decent last gen hardware.
Linux can also work, if you like a *nix style client. I've had P54D (166 Pentium) machines from post to login in under twenty. I was only starting a bare minimum of 'services' (inetd, routing, ethernet, card services) and running a very lean 2.0.xx kernel. The 1.2.xx series are even quicker, but may not have some of the device support you need..

Dos can do 32-bit through the use of what's commonly known as a "Dos Extender". Remember Doom and Quake and all those great games from the Dos era ? Ever noticed that "DOS4GW Protected Mode" startup message ?
That's the Dos Extender being loaded. Basically it's a (relatively) small loader/overlay that switches into protected mode and handles the boring chore of thunking and relaying interrupts and all that delightfully mind numbing crap.
DOS4GW was generally associated with Watcom C++, while DJGPP commonly uses GO32 as its extender although they are easily interchangeable with a few code changes (slightly different API's). Whichever extended you use, they do more or less the same things : thunking interrupts, managing flat ram (vs 16-bit segmented ram), and giving nice detailed register dumps when they crash.

IMHO having GCC or not should not make the boot longer.Concerning your need (C++ and GUI) I'd suggest BeOS or AtheOS. The problem with the latter being the lack of community. Tschüss!

Well, BeOS is fast, that's for sure. You might also want to look at the Linux BIOS page - it promises VERY fast linux loading... when the work is done.
If all you want is a GUI of some type, DOS + Win 3.1 will load very fast, if you arrange it nicely. There's a DOS version of the GNU compiler environment here, so you can do C/C++ development under DOS, but I don't know about a GUI IDE. I recall there are several text IDEs.
DOS won't take up too much space, either, so you might be able to keep Win98 on there for other boot times.
