Perhaps someone can explain to me why Windows doesn't need a pre-boot ramdisk in order to boot, while Linux does?

Linux does not need an initrd to boot, distributions do need it to support a wide variety of booting scenarios and not driving developers insane in the process.

That deflects the question.

What wide variety of booting scenarios are supported by linux that are not supported on Windows?

Windows runs embedded, headless, on rescue disks, servers, desktops...um...where is the need?

I have at least 5 different machines around here that can be installed from original MS-cd/dvd but lack support for all sorts of things. Some even don't recognise network hardware, so you need a different machine connected to the Net, and an USB-stick to download them. Hence most MS-machine come pre-installed with all of those additional drivers & patches. Out-of-the-box, most distro's recognise far much more hardware. It is now the other-way-round, compared with the situations in the 90's -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Speaking of XP - yes, the beast is still alive - I even experienced once that it didn't support USB, so I had to burn a CD with the USB driver, and then also installed the drivers for the network card, the sound card, and the video card, ...

Well, and going back to the 'initrd' topic: windows seems to reconfigure itself to boot from the hardware it is installed on - you see that when you try to boot from that disk in another PC. Therefore, I'd say, there is something similar to initrd on Windows, but they didn't do it "right", they simply got it plain wrong.

Have a nice day, Berny

[slightly off-topic, as previous post..] Well, i recently 'discovered' 130GB of spare room on the HDD of my scan&print-server-pc. As it was 'ancient', XP was on it. The discovery made me decide to see if W7 could be put next to it, and afterward oS122, with a windows boot-loader, as i heard a myth, that the service-pack would not install trough a Linux-boot-loader. (SP1 installed so quickly, that i did not have time to install oS122 on it, so i was not able to prove anything about the boot-loader myth...) The W7 compatibility test app showed absence of original chip-set and video-drivers, and audio-driver, suitable for W7. So, W7 did not find drivers for my video-card, which was Intel, Mo-Bo embedded, and cooperated with the chip-set, so the video-memory could be shared from ram via the BIOS, with the original chip-set drivers, and left me with 640x480, very disappointing. Audio-drivers it fetched online by itself, as the Drivers for my Epson Stylus C64 Photo Edition, and even updated drivers for an installed pci-wifi card, that lacked updated XP drivers, and was/is unusable with XP. W7, however, has the opportunity, to even install W95, 98, W2K, millennium and Vista applications via problem-solver>admin settings. With this setting, i was able to install the XP Video-Drivers, so my resolution-settings became available, also 1400x900, my monitors default: Satisfying enough, despite the lack of some 'special' W7 possibilities. And even more: I was able to install my 'ancient' HP Scanjet 4100 C, with the original Win98 drivers, and some XP patches. A thing that was almost impossible with XP, where i had to use the alien 'Vuescan', a really very good app, which works with almost every scanner on the planet, and with all imaginable options, and far superior to the original app, except for the buttons. The buttons now bring the original interface, but they do not work with Vuescan. W7 has also a superior hw detection as to usb apparatus, compared with its predecessors. IMO, the added backward compatibility option is far out the most user friendly option ever seen in a Windows OS. I am 90% sure that all needed drivers to run the pc, are present in the default-kernel (and modules) in oS122, except maybe the scanner-driver, but i still have to check. -- Have a nice day, Oddball.

This is another side point. I'm not talking about installation. I'm talking about why initrd is needed AFTER the OS is installed w/all it's drivers -- i.e. during normal usage. Windows doesn't need extra disks / drivers to be pre-loaded unless you are booting from a rescue disk/installation disk. Once you have it installed, Windows doesn't need such things. Why does linux need an initrd? It seems the SuSE folks are saying this is a requirement of the linux kernel -- yet windows doesn't have any similar analogous need. So why does linux need this? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

You have followed the links to the Wikipedia articles describing the boot mechanisms in various Windows versions that David posted yesterday?

But since most people don't read Factory, the discussion will not gain traction if it does not appear on the most popular list(s). In fact, suggesting it only appear on Factory is like telling Linda to shut up and go stand in a particular corner where she can be ignored. A classic shut them up or shout them down tactic.

John, Like it or not, the main list is for discussion of the currently supported release(s) and hopefully Evergreen. Discussion about the future from a technical perspective is -factory.

From a conceptual perspective it would be -project.

FYI: -factory is an active list, so I totally disagree with your premise. In fact I believe the opposite is true, the majority of the "technical contributors" and decision makers are on -factory, much less so here.

As such changes would only be done for future versions and never for released ones, the place is opensuse-factory.

Why should I?

As I wrote: if you give references for others to read, it's much better to give online references so that other folks can read up directly and maybe discuss in more depth.

I've read the Windows system internal's book written by a Windows "Fellow", that describes the process in considerably more detail in chapter 13.

I got that. But only few people will actually buy a book only to educate them for a discussion with you, wich was the reason I mentioned the wikipedia articles.

(5th ed). It tells you why -- boot sector loads a basic device aware booter like lilo, that can then boot images off of any of windows devices... None of them require an initrd.

How does it then load, let's say a SCSI driver to access a SAS disk? AND it limits your choice of file system for the boot device. So I'll rather take an initrd and don't have the severe limitations the windows way of booting has.

several posts, but you seemed to be a case-in-point of not getting the fact that if it was NEVER appropriate to cross post, it could be blocked for everyone at the list-reflector.

No, because there are cases where cross posting would be appropriate and anyway you can't really solve social problems in a technical way. Philipp -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
