New Post: How to use Cosmos with VirtualBox ?

zdimension — Thu, 23 Feb 2012 10:54:46 GMT

I've tested in C# and it always shows you know what.

And for set it on release mode, click in the VS2010 toolbar -> ComboBox "Debug, Release, Configuration Editor" or set it on "OSNAMEBoot" Properties ?

Sorry for my bad english I'm french

Commented Issue: VMWare SVGA driver update command causes crashes [14755]

Trivalik — Thu, 23 Feb 2012 10:49:33 GMT

When I use the Update command on VMWare SVGA, it causes my OS to crash with no error information. This has also been found by HD2HD and blah38621.
Comments: ** Comment from web user: Trivalik **

On debugging with gdb, on label: System_Void__Cosmos_Core_MemoryBlock_set_Item_System_UInt32__System_UInt32_.001A

it bring the instruction: mov dword [EBX], EAX
EBX = 0xD8000004
EAX = 0x00000001

where the exception in vmware occure.
It is therefore in WriteToFifo(1) call in Update().

Are there any docs how it should work with this FIFO?

BTW I'm using MS4

Why use MS4? You should update to 87612 or DevKit!

I did but for some reason .net Framework is not compatible with Visual Studio C# 2008 Express.I'll just try to update my 2008 version to 2010 C#.

Update your .net Framework.

The Line " var ram = Cosmos.Core.CPU.GetAmountOfRAM(); " needs the Cosmos.Core reference requires Net. 4.0 Framework and Visual C# only go's up to 3.5 .

I've tried updating but for some reason whenever I compile in Visual Studio 2010 it gives me an error and when I go to open up a new Cosmos Project it is empty.So I have to use Visual C# Express Edition until I can resolve this.

I've done the RTC but for some reason it shows me just the number of the hour in 24-hour format and a male smiley symbol next to it.

If you have used the old link, ignore it and use this one

Did a little bit of debugging and your code is perfect, only the update command is broke. The error I get from VMware when using the update command:

VMware Player unrecoverable error: (mks)

Invalid SVGA FIFO registers.

Note: I was able to set mode and pixel, now you cant see the pixel till you update

When I called the update command I got this error. I believe the issue lies somewhere in the drivers FIFO registers,

If I spend some time I may be able to track down which one causes the issue. Thanks - Matt

Cosmos, please look into this.

for the amount of ram i can you help you out !

just use this :

var input = console.Readline();
if (input =="getamountofram")
{
   var ram = Cosmos.Core.CPU.GetAmountOfRAM();
               Console.WriteLine("Your system has:");
               Console.WriteLine(ram + " "+"MegaBytes");
               Console.WriteLine("of ram memory");
}

hope this already helps !

To get the time and date you would use Cosmos.Hardware.RTC and Ram is Cosmos.Core.CPU.GetAmountOfRAM(); I know the RTC works in MS4, and I believe the GetAmountOfRAM does as well. Hope this helps - Matt
