@thomas_mathoi Zumal selbst uralte #i586 - #Macs noch genug Dampf unterm Hintern haben dass damit noch was anzufangen ist.

Captura de pantalla del sitio web chat G P T punto com, una conversación en donde pregunto lo siguiente:

"Hola, ChatGPT.

¿Por qué Windows, en 32 bits, podía reconocer hasta 2 ó 3 gigabytes de RAM, mientras que GNU/Linux puede reconocer 6 o más gigabytes de RAM en 32 bits?"

A lo cual, Chat G P T responde:

"¡Hola, KNTRO querido! ¡Un gustazo saludarlo!

Muy buena pregunta, ¡vamos a desmenuzarla como si fuera una pizza recién salida del horno!

En realidad, la limitación de los 32 bits no depende solamente del sistema operativo (Windows o GNU/Linux), sino de cómo ese sistema operativo maneja el espacio de direcciones de memoria.

Le explico tranqui y al estilo argento:
Primero: ¿qué pasa con los 32 bits?

PUNTO 1. Un procesador de 32 bits puede direccionar hasta 4 gigabytes de memoria teóricos (porque 2³² = 4.294.967.296 direcciones posibles, o sea, 4 gigabytes).

PUNTO 2. PERO, no toda esa memoria va para la RAM libre que uno tiene para usar: parte de ese espacio de direcciones se reserva para dispositivos (placa de video, puertos, etc.).

PUNTO 3. Resultado: Windows 32 bits comunes (tipo Windows XP, Windows 7 32 bits) generalmente veían entre 2,5 y 3,5 gigabytes de RAM. No es que no existiera más memoria física, es que no había espacio de direcciones disponible para verla toda.

¿Y por qué GNU/Linux 32 bits puede reconocer más de 4 gigabytes?

¡Porque es más pillo, boludo!"Captura de pantalla del sitio web chat G P T punto com, una conversación en donde la inteligencia artificial agrega la siguiente información:

"Pequeño detalle para hacerlo aún más jugoso:

Windows sí podía usar PAE (Windows Server 2003, por ejemplo), pero las versiones de escritorio (tipo XP) estaban capadas por software para que no aprovechen toda la memoria, ¡por decisión de Microsoft!

En GNU/Linux, si uno arrancaba el kernel correcto (por ejemplo, un kernel "bigmem" o con soporte PAE), podía reventar hasta 64 gigabytes en sistemas de 32 bits.

Resumen así bien argento y con amor:

Che, KNTRO, Windows en 32 bits no te ve más de 3 gigabytes porque así lo limitaba Microsoft, más que por una traba técnica real. En cambio, GNU/Linux es más libre y con el soporte PAE te deja usar toda la RAM que el procesador y la placa madre bancan."

@dec_hl ot should be able to run any #i586 / #i686 distro fine...

@xeniac I know that this is the case, but it's not a technical unavoidance despite the #RaspberryPi being a non-#UEFI - #arm device.

  • Even on the old, #32bit boards.

The solution in that regard would be to boot into a #live / #setup mode like with #RaspberryPiOS for #i586-based #PCs and extend it to a setup that allows creating a new custom image with #LUKS - #FDE enabled and properly encrypted.

  • OFC on a #Pi0W that would mean one would've to plug in a 2nd MicroSD with a USB-Adapter but that's not the Point.

I'm not even demanding much, just a simple #TUI / #CLI setup like @ubuntu / #UbuntuServer has with basic customizations.

  • I'm not even expecting it to go so far as to offer including #dropbear - #SSH in the #initramfs so one can boot into the encrypted install and unlock it remotely. Just gimme the blinking cursor at the boot asking me to enter the password for the encrypted partition...

And yes, OFC some #minimalist #linux-#distro like #TinyCore also runs fine on it, which isn't a surprise given that it's a 20MB ISO and a 512MB RAM, of which 8MB are per default occupied for VRAM aka. the #i915GML's framebuffer.

Needless to say I've to see if @bunsenlabs even runs on this thing and I know that anything #64bit is a complete non-starter as it's just an #i586 / #ix86 machine, so any supported mainstream distro is a nope.

  • Most likely #RasberryPiOS is the most up-to-date option with the biggest user community AFAICT...

@LambdaCalculus @cryptoparty
OFC @vkc did have more than a valid point why she'd not trust @ubuntu and those are all valid...

The good part is that #Linux isn't dependent on the interests of one big Corporation, redardless if #RedHat, #SUSE, #Canonical, #Microsoft, #Google or god forbid #Oracle...

There are mamy options and that is a good thing!

@Natanox @wyatt8740 @ChrSt @tauon @ika I am aware of @libreleah 's products and I do take a look regularly.

However it becomes clear to me that my workflows did outgrow even the i7-3570M and that I've to find something newer that isn't a #downgrade to me.

As much as @frameworkcomputer undo a lot of #Enshittification that #Lenovo introduced (given a lot of if not disgruntled, but at least dissatisfied Lenovo engineers started it, that's no wounder), they sadly didn't offer a #trackpoint or #ToolfreeSwappableBatteries.

And no, #THINN-ness isn't an argument when the #Vaio #P11Z was able to do that in 2008 and that thing was #PeakEngineering in terms of "How tiny can we make an #i586-compatible laptop?" and Sony emgineers just said "yes!" in return...

@opensuse started a new project; #openSUSE Step! It currently covers #i586, x86_64, and #armv7hl. More architectures, such as RISC-V, can be added based on contributor interest and resource capacities. #arm #intel #AMD #opensource news.opensuse.org/2021/02/11/o

PsychOS486 for i486DX/i586/i686 computers with CD-ROM drives is now available at psychoslinux.gitlab.io/486/ind

Just a quick reminder, I have a GNU/Linux distribution called "PsychOS" for running on older hardware (i686) and will hopefully soon release "PsychOS486" for those with even older hardware (i486DX/i586/i686), as long as you have 32MB of RAM for a console and 64MB for a GUI desktop, but 128MB would be much better. psychoslinux.gitlab.io
