Post subject:  Mac OS 8.6 ROM

Is the ROM from the Mac OS 8.6 CD [or the 1.0 Update (1999)] really working with SheepShaver 2.2.8?

If anybody is running Mac OS 8.6 with this ROM, which Linux Distro and which Sheepshaver Version are you using?

I have tried Mandrake 9.2 + Sheepshaver RPM. I don't have Internet under Linux, so i couldn't try the CVS.

Thanks

The rom from the Mac OS 8.6 CD does work.
You have to extract it before you can use it.

Im using the l8est Sheepshaver (The one that was released a few days ago with the improved performance, its on cvs). Its running fine for me on fedora core 1 and mandrake 9.1

Thanks! How do i extract the ROM? > I have a 2 Mbyte File called "Mac OS ROM". Isn't that the right size/file?

If i use it in SheepShaver i just get a grey screen and no Smiling Mac or any other icon etc. There's no error message. So the rom seems to be valid but it's not loaded..?

Thanks

Post subject:  when i used that rom

i use that rom image as well...i noticed the first time i tried booting off it, it did the same thing... i rebooted SheepShaver several times...then i walked away and let it sit trying to boot for like 15 minutes..when i came back it was botting off the rom... slowly..after that i rebooted it again (after if booted from the cd fully) and it now boots up with good speed

It's working! Thank you! I just had to wait a while...

Ok, it's running, but i still have one problem! How do i switch to 1024x768 Fullscreen?! It's always loading the system in a window (800x600).

Is the fullscreen-mode working at all?

Thanks again

I don't think fullscreen mode works at this time. At some point, I started to merge B2 code for runtime depth switching too. However, I put that on hold as I am adding AltiVec emulation. ;-)

I also have an 8.6 CD. (It's actually a service source CD).

Mandrake will not read the CD. Do I have to run basilisk, save the ROM to a 'fake' mac drive, then point the SheepShaver GUI to the 'fake' mac drive where the ROM would now be?

Also, I can't seem to 'browse' to the ROM in the SheepShaver GUI. It looks like I have to type in the path myself.

I ran the 'create.sh' scripts to build SheepShaver and Basilisk. I can't seem to find the Basilisk executable binary.

I guess I'll have to run Basilisk from Windows.

Did the create.sh scripts build the latest version of SheepShaver, the one that is capable of booting from the 8.6 ROM?

what is AltiVec emulation?

AltiVec is an instruction set found in G4 processors (essentially the difference between some G3s and G4s of similar clock speed), which results in pretty good speed increases for applications supporting AltiVec.

How can that be implemented in a 604e processor though?

Now sriously what is the link to the apple mac update rom? Yes i don't own a ppc mac. just a jousy classic mac 68k quadra 650. :(

AltiVec instructions are now emulated. This increases reported PVR (Processor Version Register) to match a 7400, aka G4 processor.
