Various Woes

[NevadaDave]

Hello All,

I am running 10.4.6 (JaS load) on a Medion PC with a Microstar MS-6533-L motherboard. The chipset is a SiS 645DX. OS is loaded onto a separate 40 GB HD.

I have had a few problems with this:

1. The PS/2 keyboard is not recognized. I'm using a Logitech wireless/USB keyboard.

2. Sometimes when I boot, I get the gray 4-language reboot screen. If I shut the system down, sometimes it will boot normally, sometimes I can repeatedly press F8 and get the boot options screen. I have tried platform=x86pc and platform=acpi with generally good results. I can ususally tell if the boot will succeed because I can hear the HD heads clicking. If I don't hear them, I get the reboot screen.

3. Sometimes after booting (and it always seems to happen when I start up and then go away for a period of time) I will have the desktop, but no mouse pointer. All I can do at this point is press the power button & reboot.

4. About every third boot, when I fire up Safari, I get the message that I'm not connected to the internet. I go to preferences & click on network, select the PCI ethernet card, and then everything works.

All of these above are annoying, but liveable. However, the one that has me totally stumped is that I cannot get sound. I have the Realtek AC97 onboard sound. The vendor/device ID comes up as 0x70121039.

If I apply the kext mod as shown in a variety of places, I will get a volume indicator on the menu bar, and if I go into preferences, I will see the AC97 audio as an output device. However, if I actually try to USE the sound, whether trying the speaker setup test or running iTunes, the system locks up hard - will not respond to mouse clicks (although the mouse pointer can be moved) or keyboard. The only thing I can do is a push the power button & reboot, then edit out the string I added. I have tried adding the dev/vendor string to the ICH6, the ICH5, the ICH4 and the nVidia sections of the kext with the same result. I realize that this seems to be a common issue, and that everyone is busy with their own problems - but does anyone have anything else I can try?

Thanks much!

Why do you care if your PS/2 keyboard is not recognized? You are using a USB one.

 

This could be cause by really anything. If you want guarenteed booting success try it in safe mode [-x]

 

Check you energy saver settings. Sometimes it dies if you let it go to sleep.

 

I don't know what could be causing this.

Ramm,

I care about the keyboard because I like my PS2 keyboard better. It is more comfortable to use than the wireless one. Other than that, I suppose that there's no particular advantage (other than not having to replace batteries).
