I don't know if AnV is still watching this thread, but there is some issues with the conversion to snprintf you might want to fix.

	
	if ((subVendor || subProduct) && ((subVendor != vendor) || (subProduct != product)))
{
	out += snprintf(out, sizeof(out), "pci%lx,%lx", subVendor, subProduct) + 1;
}
out += snprintf(out, sizeof(out), "pci%lx,%lx", vendor, product) + 1;
out += snprintf(out, sizeof(out), "pciclass,%06lx", classCode) + 1;

 

This code isn't going to do the same thing as the sprintf version. What you want is something more like:

	if ((subVendor || subProduct) && ((subVendor != vendor) || (subProduct != product)))
{
	out += snprintf(out, sizeof(compatBuf)-(out-compatBuf), "pci%lx,%lx", subVendor, subProduct) + 1;
}
out += snprintf(out, sizeof(compatBuf)-(out-compatBuf), "pci%lx,%lx", vendor, product) + 1;
out += snprintf(out, sizeof(compatBuf)-(out-compatBuf), "pciclass,%06lx", classCode) + 1;

 

The second parameter to snprintf is how many bytes to write. When you put sizeof(out) in there, you are telling it to write 8 bytes (on a 64 bit os). snprintf will return -1 if there isn't enough room, but will return the length needed if you pass it a size of 0. In this case, it shouldn't hurt because the string is guaranteed to fit(as is, though that may not be true if the code changes further). For example, if any of these calls exactly fills up the buffer then there would be a problem. 

	if ((subVendor || subProduct) && ((subVendor != vendor) || (subProduct != product)))
{
	written= snprintf(out, sizeof(compatBuf)-(out-compatBuf), "pci%lx,%lx", subVendor, subProduct);
		if(written>=0){
		  out +=written+1
		} else {
		  *out = 0;
		}
}
   if(sizeof(compatBuf) > (out-compatBuf) {
 written= snprintf(out, sizeof(compatBuf)-(out-compatBuf), "pci%lx,%lx", vendor, product);
 if(written>=0){
	out +=written+1
 } else {
	*out = 0;//if a partial copy is okay you can do *(out+sizeof(compatBuf)-(out-compatBuf)-1)=0
 }
}
if(sizeof(compatBuf) > (out-compatBuf) {
 written= snprintf(out, sizeof(compatBuf)-(out-compatBuf), "pciclass,%06lx", classCode);
 if(written>=0){
	out +=written+1
 } else {
	*out = 0;
 }
}

 

A dynamic buffer could also be used:

			
		UInt32 size = snprintf(NULL, 0, "pci%lx,%lx", subVendor, subProduct) + 1;			
		size += snprintf(NULL, 0, "pci%lx,%lx", vendor, product) + 1;
		size += snprintf(NULL, 0, "pciclass,%06lx", classCode) + 1;

		char* buffer = new char[size];
		out=buffer;
					int written=0;
		written+=snprintf(out+written, size-written, "pci%lx,%lx", subVendor, subProduct) + 1;			
		written += snprintf(out+written, size-written, "pci%lx,%lx", vendor, product) + 1;
		written += snprintf(out+written, size-written, "pciclass,%06lx", classCode) + 1;
		....
		delete [] buffer;

SLICE had made that SL version already !

I dont know the link but attatched that new SL IOPCI here.

Be sure to fix rights (sudo chown -R root:wheel ....) before using it and also update .mkext (normaly automatic or do an sudo touch /System/Extensions )

 

The attatched IOPCI is Snow Leo ONLY!!!

hi mitch, thanks for attaching that kext. I already tried it before and it does not have any positive effect on my system.

 

An old version from Chun Nan (he made it for 10.5.6) is Snow Leo compatible and offers the remapping I need for getting LAN & WLAN miniPCIe to work. I attached it. It does not work in /Extra/Extensions but only in S/ L/ E.

 

Now the only thing not working on my Snow Leo 10.6.1 HackBook is wake-up from Sleep (black screen).

That problem may not be fixed (only) by that modded .kext. It fixes only some interut handling and make sd-card readers seen. Mostyl nothinh to do with sleep. At least sleep with 10.5.8 + SL is more problematic that Version up to 10.5.7.

Does anyone have a working IOPCIFamily.kext for Snow Leopard, that works on an Acer Aspire 5920G? I have tried several of this thread, and none seem to crash my machine, but don't seem to do anything either - wireless card and ethernet still not picked up (I have replaced the built in wireless with an Apple Airport N Broaccom card).

 

I also have the source for the kext, and providing someone can point me in the right direction as to what I need to edit, I am willing to give it a go. I will make the kext available too in case it helps anyone else.

 

I'm not bothered about getting the cardreader working, but graphics and wireless are my two main issues I would like to get resolved. Cheers in advance.

 

Edit: Post 58 (BugsB) had a link for a kext which has sort of worked for me. I'm now getting the Airport icon but can't turn Airport on. So near yet so far! As for remapping, if someone can tell me what to look for or change in the source to get mine to work, I'll try and help others also.

 

Edit 2: After a reboot the airport card worked fine, and is connecting to networks fine with no issues. Gfx is still a no go, and no ethernet as yet.

Hi ^^

 

I have a problem on my Aspire 5739g (Cantiga PM45) with Snow 10.6.5

The Lan and Wifi don't work.

 

Reading the Ioreg I noticed that Bridge IORanges and MemoryRange are respectively 0x0 e 0xfff and they are the same for others Pci Bridge

The Lan card's error is:

 

localhost kernel[0]: [AttansicL1eEthernet] Error: Couldn't map io regs

localhost kernel[0]: [AttansicL1eEthernet] Error: Couldn't probe adapter

 

How can I solve these problems ? This kext can be the solution?
