BIOS is an acronym that stand for Begin in Open State.
The BIOS is a piece of software. It is resident inside the PS2 read only memory and it takes the hand when you turn the PS2 on. It looks for any CD'rom or DVD-rom, and when it finds any one it reads the tracks and loads the tracks contents (some game software) into the memory of the PS2. Then this software takes the control of the PS2 and, oh miracle, your awesome game starts.mitug said:ok, i'm not asking for the bios, i just want to know what it is? and y do i need it? what happends if i dont have it, and what happends if i do? what is the difference between the built-in-homemade-PCSX2-BIOS and the BIOS in the original PS2? if i get the BIOS from my PS2 to my PCSX2, will it be better to use it instead of the built-in-homemade-PCSX2-BIOS? if yes, y? if not, y?
please answer me, i know those questions are newby questions, but i am a newby in this.
both answers are no, but you will have a lot more luck with the BIOS than without it.mitug said:realy thx for the answers. now, lets say i dont have the bios in the PCSX2. will games work for me? and if i do have it, will games work for me? (if the answers for both of these questions are "no", what do i need the bios in PCSX2 for?)
and if i run them (the commercial games) with a bios, will they run?zizozac said:and i add for that without Bios you will not able to run ps2 commercial games
It's a very nice question and i'm very happy you ask it. By the way do you want a coke or a scwheppes ?mitug said:and if i run them (the commercial games) with a bios, will they run?
I've never heard BIOS standing for that, i work as a Computer technician, and it has always been understood that BIOS stands for "Basic Input/Output System".Squigi63 said:BIOS is an acronym that stand for Begin in Open State.
Interesting, so it might be possible to kick off the BIOS and replace it e. g. with a suitable Linux-Kernel as possible on PCs? (yes, it is possible to run a PC without a typical BIOS. But please, don't try if you don't exactly know what you are doing, you have been warned)asatru said:I've never heard BIOS standing for that, i work as a Computer technician, and it has always been understood that BIOS stands for "Basic Input/Output System".
What a bios is and does is this:
It is required for most interactive electronics to work, it is a piece of software that runs at the most basic level to allow for the machine to even function.
if your psx or ps2 didnt have a BIOS, or it became damaged, you would just get a blank screen when you turned it on.
You know how on your ps2 you have the browser menu, and the configuration menu..... this is all software included in the bios for "Basic" functioning.
on your ps2 the bios tells the video how to display, it tells the ps2 how to receive and interpret input from the controllers and remote. it is a hardware "Driver", it allows for the Firewire port to work, and it allows the USB ports to work.
your ps2 is actually a computer scaled way down.
you can run an operating system on it ( see the Linux Project for PS2 ), and the BIOS is just a bunary file that loads at boot-time.
your ps2 is basically a motherboard, CPU, video card, sound card, usb port, firewire port, and cd drive. these pieces are all brought together in working order by the bios
No, you do not need BIOS-Routines, you can access hardware directly. You just need to make the kernel suitable and put it to the place the hardwired routines are looking for. (e. g. EEPROM) Of course that means to overwrite the BIOS, so it's really dangerous, if you don't have an extra flash device.I-Chan said:I think you are mixing concepts. The bios starts the system as it is. When you turn the system on, it's hardwired to boot to the bios. The bios initializes devices on the system and has the method for starting it, be it launch a part of itself as gui (like in most consoles), or look in a predesignated area of memory to load the OS (like in pc, looking in the boot device's system block). Afterwards, you may or may not use the methods provided by the bios to access the system components, but the bios must be there. And in consoles, most of the times the bios procedures are used.
