Strange Boot-up Issue

[viriiman]

After reading around, it seems that my issue with video is a unique one.

 

 

I'm currently running a Toshiba Satellite M55-S135 which (on bootup) shows that its an "Intel 915GM/910ML/915MS Graphics Chip".

 

I was running OS 10.4.1 on the machine with ZERO video problems when I decided to upgrade to OS 10.4.5. Dowloaded the DVD (it was prepatched), installed and rebooted. Here's the fun part.

 

If I boot the machine up normally, it runs through a whoooole bunch of lines of text (too fast to read) and then goes to a black screen and stalls.

 

If I hook up an external monitor, same thing.

 

Here's where I got creative. After accidently pushing the install DVD back into the drive, I noticed that with the external display unplugged, the boot sequence went futher then when the DVD was out of the drive, but it did NOT boot all the way into the OS.

 

Now, if I put the install DVD in the drive (and let it time out) AND connect an external monitor, the computer boots all the way into the OS (w/ out any switches) and I'm able to eject the disc and put in anything I want (once I'm in OS X). However, once I'm in OS X, I'm unable to disconnect the external monitor (or I loose the display). Also when I check in display, I only see one (and not two).

 

I have no idea as to what this is and how to fix it, but I hope someone does, as this seems to be the oddest thing. On a side note, I tried to use the "fix" first mentioned in this thread, but I don't had the AppleIntelIntergratedGraphics.kext file

 

 

 

TIA!

did you try reinstalling OSx86. My computer does a simillar boot thing, but if i leave it, it usually boots in about a minute.

Will try tonight. After reinstalling, I'll eject the disc and let the laptop try and boot up overnight. If it's not up in the morning, no dice. I'll post the results tomorrow.
