Or they use a naming scheme that makes it easy to be confused with "what you think it is". Many years ago, I wanted to buy a Realtek RTL8029 network card. My local shop had them, with the name "Net8029". So I bought one, but said I would return it if it wasn't supported by the Realtek driver. And as you may have guessed, "boot -v" later, it was a different chip, and the driver didn't pick it up. I made an (impressive looking) dotmatrix hardcopy of the boot process, marked the problem with crayon, and returned the card. :-) > > > I've been using IBM / Lenovo, Dell, Siemens- > > > Fijutsu and Sony laptop hardware, and FreeBSD did not > > > have any trouble getting the buildin hardware to work. > > > Still there are models which cause problems: Some of > > > them use chipsets not supported by current drivers, others > > > just use f*cked up ACPI implementations, and others > > > delegate hardware functionality to proprietary drivers > > > which make the actual devices "appear" and "work", and > > > as you will guess, those are only available for specific > > > versions of "Windows". > > Like winprinters. Blegh! Yes, those are terrible and years behind technological evolution. The same applies to "WinModems", a disease that development has fortunately dealt with. I remember that this kind of stupidity started (in the PC world) on late DOS: Soundcards that no "driver" (sound subroutines in the programs) would recognize until a DOS program, loaded via CONFIG.SYS, would have sent a firmware to it, initialized and enabled the card. Then everything worked as expected, a "Sound- blaster or 100% compatible" was suddenly present. Of course I never owned such a card myself. :-) > > > It depends on you if you want to: > > > > > > a) purchase other hardware to replace what is > > > not supported, > > > > > > b) relapse to using Linux which supports your > > > hardware, or > > > > > > c) accept that it's not working and make a better > > > choice next time you buy something. :-) > > If I'm buying a PC or laptop I tend to go to a shop with a FreeBSD DVD or > memstick and ask if I can try booting the machine in question from it.

A FreeBSD live system such as FreeSBIE has been very useful in the past, sadly they didn't update it past v5. > Smaller shops can generally build PC's and sometimes laptops to order with > components that you specify. That is generally what I do. Me too, except that I still assemble the stuff myself.

This is something I recently recognized: People spend lots of money for "top notch CPUs" and systems, but the speed on which the whole thing is working isn't any impressive. Especially when loaded with "Windows", it's sometimes less than "what they had before", and they start complaining. BUt hey, "it was expensive, so it must be good!" As with used office laser printers, buying "older" hardware for much less money and relying on FreeBSD and its applications to efficiently use those resources looks more appealing. Less money, more usable power. > These days the biggest speedup for a computer is probably to use an SSD instead > of an HDD.

SSDs are becoming cheaper, and TRIM support will surely appear in GELI, so if you can wait, wait a bit. And: Yes, SSDs for mass storage are an improvement that you can actually see (see "newest hardware" mentioned above). -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
