hi, i'm just a new member from France (sorry for my english), and i tryed to install Longhorn 4074 as a VM in Virtualbox 3.2, using the date bios setting VBoxManage modifyvm 7121dd50-f955-4f92-8157-f789b0d2d818 --biossystemtimeoffset 198460800000. The command works but after the step 3, the VM reboot again and again at the beginning of the install.Did i missed something to run this wonderful OS in Virtualbox or is the .iso's corrupt ? Thanks a lot.

Longhorn 4074 has magic as it doesn't need a BIOS date. Just install straight away.

thanks for your response. i'd tried but it didn't work on Vbox until i made that to change the bios:

VBoxManage modifyvm 7121dd50-f955-4f92-8157-f789b0d2d818 --biossystemtimeoffset -198460800000

now, it works perfectly, but i've gotba new problem, the network driver (emulated by virtualbox: pci fast3 ethernet controller) isn't recognized.

Try a different network controller, since Longhorn 4074 is an early alpha and may not work with all hardware devices, due to driver limitations. You can't expect Beta or Alpha builds to work with everything.

Hope this helps

That's what i did and now, it works fine on Vbox. Now, 58 days left to discover this amazing OS...better than XP, better than Vista.

It does here. Try editing .xml instead of issuing VBoxManage command maybe?

...works fine now, i've patched it with a different winlogon.exe to replace...for informations, ccleaner and clamwin runs on Longhorn without problems. see u soon. thanks for all...

Thanks for the tutorial. I hope when I manage to get some beta builds of timebombed OSes, I'll find this really handy.

It did for me.

hi,

i've got a stange problem, i can't install Longhorn 5048 (x86) on Virtualbox 4.04, its starts installing and then i've a display crash...i didn't have that problem before with Virtualbox 3.xx. did someone else got the same problem ? before installing, i've prepared the partition using GParted. i run VBox on a Dell Studio with ATI Radeon graphic card (256 Mb). thanks to all.

I recommend that you uninstall Oracle VirtualBox 4.0 and install the latest Oracle VirtualBox 3.x release.

If you want to install Beta's, install Oracle VirtualBox 3.x
(Most people have problems with Beta's in Oracle VirtualBox 4.x).

I have Whistler 2410 installing, high colour, bios time offset set back...
in VirtualBox 4... No problems. But VBox is not the best for betas, at all... I'd recommend DOSBox or Virtual PC for anything that recognises an S3 video card.

As I said and I quote:

Read that and especially read the bold part.
I never claimed that everyone has problems, most people have problems.

As I would recommend:
- Microsoft Virtual PC 2004/2007 (some will work in both, or just one of them) with the MS-DOS Based (1, 2, 3), 9x Based (95, 98, Me), NT Based from 3.1 until somewhere around XP Beta 2.
- VMWare Workstation 4/5/6/7 (I use 7.1.3) for some NT's that do not work in VPC 2004/2007 and from Windows XP Beta 2 and above (where VGA.DRV SYS works with the SVGA of vmware)

For if both do not work, Bochs or Qemu (if you can understand Qemu)

Thanks! Now I know a little more about the BIOS in Virtualbox. I use Virtualbox a liitle, but most Virtual PC!

I just got the newest beta of VirtualBox (aero, yay!) and I'm planning to install betas on it, so this should be handy.
EDIT: Doesn't work on new VirtualBox

awesome... Thanks for posting this.. Works for me.

I always change my computer's time to set the bios clock..

Change the date in Windows. All programs take date from Windows. But this tutorial is good. And my solution is simple, but you must set the date again and again...

...and Windows takes date/time from BIOS.

Windows 7 has a magic, it can keep date I set.

Windows 98 has the same "magic" as well, as it probably updates the bios clock on most systems.
