If someone has PCI AC97 soundriver for testing, please can you make this driver available for others?

Trust me to have a system that wont work with this driver
Motherboard's an ASUS P4S800D I think the AC97 is provided by SiS although I'm not certain (My N/S bridges are both use SiS chipsets but my LAN & SND are not detected by the utility on the SiS website. I Know my LAN is part of the 900 chipset) I think ASUS have done some jimmy-rigging for some reason. |

Ivan: you're right - your player works in RE (and only in RE#8 now). Why? Because official kernel allows us to use ports 0000-3FFF but your player uses ports C000 and higher so i can't test it until RE#8 is released.

drhxx, the code may still work with your card, it just looks for a set vender id and chip id if your is not on the list , it will not work, but may if your vender id is check for.
Go here and get the vendor id and device id for your sound card or onboard sound. http://www.pcidatabase.com/ and send it to me i will put in the code to search for it and then you can try it. \\\\||//// (@@) ASHLEY4. Last edited by ASHLEY4 on 03 Oct 2004, 20:45; edited 1 time in total |

drh3xx, i have up dated code with your id etc. it may work, if not let me now and i will get data sheet for your vendor and see where the differnt. is.
if you get " AC97 test driver byASHLEY4. " and then the cdplayer commands, then its detced it, but if no sound from speakers, then it needs sweeking. ps: make shore you have a cd driver to soundcard cable, some new pc do not have them. \\\\||//// (@@) ASHLEY4. |

I custom build all my PCs
Hell I'd have tried to built my own router if I could afford all the kit. I thought you'd have known me a bit better than that ASHLEY4. As for your code, it shows the menu but still no sound
You still gonna hit that wednesday target you set yourself? I'll be away until then but I'll drop by your site as soon as I get back. |

The cd cable bit was not meant for programmers like you drh3xx, it was for the more general user who is not in to programmer.
Thats Y i did not put a type in your vendor id here etc, in the code, i would get lots of what is a vendor id ?. As for Wednesday target do not expect too much. \\\\||//// (@@) ASHLEY4. |

i tested your app with my via ac'97 audio controller and it sdidnt worked, i get this error in the debug board :
Quote: Error: Could not find Intel ICH based AC97 audio device! is this because my card isnt recognized or isnt it gonna work at all? What do i have to change/or what info do you need to get it working?[/quote] |

Ivan has no any VIA-dedicated documents, so VIA-chipsets aren't supported now. If you have some - send it to him.

I am working with the ac97 sound,making drivers for my OS, here is a link to a pdf with info for the
via vt82c686a with ac97 may be the one on your board ? http://www.o3one.org/hwdocs/amd_chipset/via_686a.pdf From page 106, but to get it to work, you need to use a differant method then intel ac97. its more like the Sb pro. \\\\\\||////// (@@) ASHLEY4. |

I never made drivers before, is there a sort of step by step guid to this ? I have lots of free time on my hands to learn it  |

Basic tut for make sound driver, all gather round.
Step 1. First you write a function to read PCI , we will start with dos . Code: ;===============================================================; 8/16/32bit PCI reader;; Entry: EAX=PCI Bus/Device/fn/register number; BIT30 set if 32 bit access requested; BIT29 set if 16 bit access requested; otherwise defaults to 8bit read;; Exit: DL,DX,EDX register data depending on requested read size;; Note: this routine is meant to be called via pciRegRead8, pciRegread16,; or pciRegRead32, listed below.;; Note2: don't attempt to read 32bits of data from a non dword aligned reg; number. Likewise, don't do 16bit reads from non word aligned reg #;BIT30 EQU 40000000hBIT31 EQU 80000000hPCI_INDEX_PORT EQU 0CF8hPCI_DATA_PORT EQU 0CFChPCI32 EQU BIT31 ; bitflag to signal 32bit accessPCI16 EQU BIT30 ; bitflag for 16bit accessVIA_VID equ 1106h ; VIAPCI vendor IDVIA_DID equ 3058h ; VIA device IDpciRegRead: push ebx push cx mov ebx, eax ; save eax, dh mov cl, dh and eax, NOT PCI32+PCI16 ; clear out data size request or eax, BIT31 ; make a PCI access request and al, NOT 3 ; force index to be dword mov dx, PCI_INDEX_PORT out dx, eax ; write PCI selector mov dx, PCI_DATA_PORT mov al, bl and al, 3 ; figure out which port to add dl, al ; read to in eax, dx ; do 32bit read test ebx, PCI32 jz @f mov edx, eax ; return 32bits of data@@: mov dx, ax ; return 16bits of data test ebx, PCI32+PCI16 jnz @f mov dh, cl ; restore dh for 8 bit read@@: mov eax, ebx ; restore eax and eax, NOT PCI32+PCI16 ; clear out data size request pop cx pop ebx retpciRegRead8: and eax, NOT PCI16+PCI32 ; set up 8 bit read size jmp pciRegRead ; call generic PCI accesspciRegRead16: and eax, NOT PCI16+PCI32 ; set up 16 bit read size or eax, PCI16 ; call generic PCI access jmp pciRegReadpciRegRead32: and eax, NOT PCI16+PCI32 ; set up 32 bit read size or eax, PCI32 ; call generic PCI access jmp pciRegRead Step 2. we fill in the vendor id and device id to see it is on the pc, to do that we need a function to scan through pci space to look for vendor+device id like this. Code: ;===============================================================; PCIFindDevice: scan through PCI space looking for a device+vendor ID;; Entry: EAX=Device+vendor ID;; Exit: EAX=PCI address if device found; CY clear if found, set if not found. EAX invalid if CY set.;; [old stackless] Destroys: ebx, edx, esi, edi, cl;pciFindDevice: push cx push edx push esi push edi mov esi, eax ; save off vend+device ID mov edi, (80000000h - 100h) ; start with bus 0, dev 0 func 0nextPCIdevice: add edi, 100h cmp edi, 80fff800h ; scanned all devices? stc jz PCIscanExit ; not found mov eax, edi ; read PCI registers call pciRegRead32 cmp edx, esi ; found device? jnz nextPCIDevice clcPCIScanExit: pushf mov eax, edi ; return found PCI address and eax, NOT BIT31 ; return only bus/dev/fn # popf pop edi pop esi pop edx pop cx retEnd Step 3. we need to put it together and call the above functions. Code: mov eax, (VIA_DID shl 16) + VIA_VID call pciFindDevice jnc @f; couldn't find the audio device! push cs pop ds lea dx, noVIAMsg mov ah, 9 int 21h jmp exitnoVIAMsg db "Error: Unable to find VIA based audio device!",CR,LF,"$"@@: Step 4. put the above code in to a com file (adding org 100h, etc) and boot it from dos or bootprog you can get it here: http://alexfru.chat.ru/epm.html Print one message for found and an other for not found. Step 5. well i think that enough for now, tune in for the next instalment of basic sounddriver making. good links: http://www.pcidatabase.com/#notice PCI code by (jeff leyda) \\\\||//// (@@) ASHLEY4. |

Hi Ashley4,
I just tried your AC97CdPlay.zip, as I am desperately looking for a DOS driver for my Toshiba Notebook, Chipset Intel 830M, which has an AC97 Audio Controller, Device ID 0x2485. Linux does identify it ('cat /proc/asound/card1/ac97') as Cirrus Logic CS4299 rev D. Your Program (as tested under M$-DOS and FreeDOS) says: "AC97 test driver, by ASHLEY4.", then I get the cdplayer commands. Open does work. Hitting P turns on my CDROM LED, but no sound ... 
(btw. there is not way to quit the program besides reboot...) any hope for me?? Frank |

Here are some note, first if you get "AC97 test driver, by ASHLEY4." this means that it has detect your vendor ID and device ID, this does not mean it will work, what i did was put all the vendor + device ID in that i new had a ac97 chip.
I did not have the above chip to test it on, the problem is this, the ac97 codec are 99% compatable with each other, but the address and way to enable them is totally different, so you still need to write a drivers for most vendor .
The test program comes with a bootloader which is put on the boot sector of the floppy, if you put the floppy that it put its self on. in the floppy drive and rebooted, it would boot to the program, so no need for dos, so as it made to run without dos there s no int 20h etc, i can make one for dos if people wanted it. Also if the light is on then the cd is playing, when you press to test do you here a pop as the speakers are turned on ?. Basiclly each vendors ac97 needs two to three days work and a pc with the chip on to get it to work. \\\\||//// (@@) ASHLEY4. |
