Go ahead and use it any way you want. I only ask that you give credit to me and Christopher in the documentation somewhere.

I've got a 640x480x256 linear mode working in a test program now, so I'm attempting to code a full driver right now.

I have code for that vesa mode for my OS, with fonts if you want it let me know.
ps: i am looking for people with a AC97 onboard sound ,to test a driver i am do for that chip, do you have one ?. \\\\||//// (@@) ASHLEY4. |

Sure, I'd love to see your VESA code. Anything that saves time is good.
I'm sorry, but I don't have AC97 sound; I only have a rather oddly implemented ESS Maestro 3 in my laptop. (Odd because it shares some circuitry with the modem) |

Here is some simple lfb 640*480*256 vesa code, to get you started,let me know if you need more.
This code will be available on request. \\\\||//// (@@) ASHLEY4. Last edited by ASHLEY4 on 28 Sep 2004, 14:15; edited 4 times in total |

I've got a VIA AC'97 sound on board... send me the code and an instruction, how to use, and I'll test it!
email: look at my profile! |

i don't understand, how to use it. what's the device ID?

ASHLEY4 24 Sep 2004, 23:39
Here is a place you can get info on device id http://www.pcidatabase.com
Things like soundcards, graphic cards, modems etc. have number on there chips to identify them. so if you want to know what sound card is on a pc you write to a address and it give's you a number, if the sound is made by say "intel Corporation" you would get back "0x8086", but intel make alot of chips, so you need to identify which one, so you write to another address to get that number and that number is called a device id. \\\\||//// (@@) ASHLEY4. |

The GNU <b>lspci</b> command, handily available on a BBC (www.lnx-bbc.com), usually can extract Make, Model, and other useful info on PCI entities.

Ashley4, the code works; thank you! It will be very helpful as I work on this VESA driver.

I have VIA AC'97...

Glad it works crc,
bubach, the driver for the ac97 works on all intel made chips (eg: ICH0, ICH1, ICH2, ICH3, ICH4 ) and some others. but not on via like(eg: vt82c686). So if you have any of the above, other than the ( vt82c686) or a differant model, let me know, so you can test it. All so, all the driver code will, use's is in/out, no OS dependent code will be used ( other than printing messages, which can be changed for your own) so will be easy converted for your own OS project. \\\\||//// (@@) ASHLEY4. |
