Please note that modes will be read from 1 until either the following number is not defined or 16 is reached. The extra data key is called CustomVideoMode with x being a number from 1 to 16. When using Windows guests with the VirtualBox Guest Additions, a custom graphics driver will be used instead of the fallback VESA solution so this information does not apply.Īdditional video modes can be configured for each VM using the extra data facility.

You won't be playing any Direct 3D games! You certainly don't need more than that for what VirtualBox supports for Video anyway. It defaults to 8MB, but changing it to 7MB has eliminated some problems for some folks. Oh, forgot to mention that less video memory allocation is actually better on VirtualBox.
Don't need them, but they're fun as is playing with virtual machine operating systems. Stupid things like Star Trek Captains Chair that don't need Direct 3D but won't run on newer Windows versions. I want 98 so I can use a few programs that haven't worked on XP since they went to Service Pack 2 and of course won't work on Vista, and not on Wine or Dosbox either. I'd just move Grub into the mbr if necessary. I wanted to keep the Vista boot loader so I can muck about with Windows all I want without Grub being effected. I actually use the Vista boot loader and BCDEasy to boot grub that is on my 2nd hard drive's Linux partition where Debian is. I've got a real drive with Vista on it (by choice, really!) I've got XP Pro, and used to do a dual-boot 98SE and XP, but figured I might as well have the latest Windows since I bought it. I'm going to try this eventually on Debian Lenny, as the only Windows I'd want to virtualize is Windows 98SE. Stuff like this is on the VirtualBox forums. The other trick is using the latest Realtek AC97 Audio drivers, the Windows 95 VXD version, and update your Multimedia Audio Controller to it. Reboot again, open up the Sci-tech control panel and you can even use 1024x768 Hi-Color!
You install the version 7 beta, restart Windows, and in Device Manager update the standard pci graphics adapter (VGA) to the Sci-Tech one in the list that appears when you choose to install a different driver and scroll through the Display Adapters to the Sci-Tech Corporation drivers. I've read that the same key for the last version 6 that they offer can also be used successfully on the 7 beta. Go to the Sci-Tech website and access their discontinued downloads where you'll be able to download the product keys for the older versions. Use Sci-Tech Display Doctor version 7 beta.
