Newbie Help - Chankast resets my computer!

Hi All,

As far as i know, i've done everything correctly, loaded an image using Daemon tools(CDI Image of RE:CV, NTSC, self boot), set which the drive to get the image from in the emu. As soon as i press Start, it has a little think then dies and resets my computer in the process! :yucky: If there was something that my computer didn't like, surely it'd just kill off the Emu right?

Here's Computer Spec:
Windows XP Home
A7A266 - E
AMD 1700XP
PC2100 768 DDR RAM
ATI Radeon 9600XT

Oh yeah, one more thing. the SSE isn't enabled, and i can't enable it through bios for some reason, just that the option isn't there. So i used a program that enables it. Could this be causing all the reboots of my computer?

Any ideas on how i could get the emu to work and stop it resetting my comp?

Please help!

i checked and as far as i know, i do have the new ATI Drivers. A Friend suggested that it might have some conflict with the new driver. In saying that, i uninstalled the driver and put back the old driver (the one on my Graphics card came with)

The results : it starts up.. i hear music and a ball going across the screen... then crashes and resets my computer... A very slight improvement.... rather than starting it up, then nothing, just the chankast whitescreen and then it crashes

Any other suggestions?

Nope, I didn't create it.

My friend has the same problem! His PC configuration is AMD athlon Xp 2000+, 256MB RAM, ATI 9200SE, Mercury mainboard(I don't know the name of the chipset but it has 266Mhz FSB), Windows XP Sp1+Direct X 9.0b+Latest ATI Drivers

He' was getting na error message about SSE(Your CPU doesn't support SSE) when trien to run Chankast(v0.25). He isn't a computer specialist so he called me and he wanted from me to fix this problem.But I knew that his CPU has this SSE support. Next day I went to his place. I tried to find a sollution in Bios, but there wasn't anything about SSE. So I had few words with some other people and they have said that's this SSE problem occurs due to the ATI card. With nVidia card, there would be no problem. But they gave me a windows register fix. It didn't work. So I searched the internet to find some good advice and I found a program called WCPUID which can enable SSE. Tried->enabled->and we could finally see the chankast window.

This is where the fun start's!!!!!
First of all I mounted an Image (DCI format) with Daemon tools, configured everything in chankast(I got my chankast running on my PC so i know how to do it)(and we had bios too :)) ) After I started game with "run GD-Rom" (I'm using chankast tools 0.25). It reseted my friend's PC. I've seen only the dreamcast screen with that blue swirl a after that->reset :-((( .So I've installed the latest Ati drivers and tried to run the game one more time. But now as started the game I could'nt see anything the Pc was reseted. I though't It could be a bad daemon tools version or virtual drive problem, so I tried to run the DC bios only with "run Bios" so the virtual drive wont be used). It was the same.

I think the problem is, that the SSE instructins are "blocked" with the ATI card and the WCPUID program doesn't enable it physicaly, but it only says to the operating system that the SSE instruction are enabled, but they aren't really enabled, because they can't be used, because Ati block's it. So everytime when chankast is trying to run SSE instructions it fails.

Sollution: 1.) Update Bios
2.) Get Nvidia card

WTF? SSE has nothing to do with the video card. The only way to avoid the SSE error (if the CPU supports SSE) is to update the BIOS of the mainbord to its latest version and enable the SSE option from there. If the option is not there even after the BIOS update then the mainboard does not support SSE.

OMG!!!!!!!!!!!!!!!!!!!!

Please read that reply ONE MORE TIME and do not try to piss me off!!!!!!!!
I've written that the ATI card "blocks" the SSE support!!!!!!!!!
It's some kind of harware conflict that you can't see because it isn't displayed in windows device manager!!!!!!
And these problem is caused by the Ati card+old Bios!!!!
The same configuration works fine with nVidia!!!!!!!
Btw: First read and then Reply!!!!!!!!!!

And my mainboard's Bios hasn't any SSE options and it works!!!!!

Great. Yelling at someone is definatly not a good way to get along. You'll get banned before you know it if you keep up that attitude. Calm down. Sheesh.

Sorry Modem for my "angry" reaction! But if someone reads only a half of my reply and reply this

it makes me very angry!!!!! But I'll try to be more polite next time!

Listen kid, I'm sick of people like you... OMG!!!11111!!!!1 I can't hear any sound. IT'S THE VIDEO CARD.
Let me explain. Since thanks to the appropriate program you could start the emulator (you saw the Dreamcast logo) SSE was enabled. The crash after the swirl happens because of the video card drivers or even an enabled/disabled feature of the video card. The solution is to get another version of the official ATI drivers (older or newer version) or to try to change some options from the video card configuration.

EDIT: There is also the possibility that the crash happens because of the program that "enables SSE" but in that case the video card has nothing to do with that.

Hey!!!! I don't wanna fight ok?? Sorry for my reaction but I was very angry!
I didn't want to be so unpolite to you!

Now back to the "SSE problem"

I don't think it's the video driver!!! Because when I unnistalled the card's driver it didn't work! And the program enabled SSE, of course, but when chankast runs the game and when Ati card+SSE instrructions are used together->>>reset
That's why the Ati card users have SSE disabled. I think that mainboard detects
this problem and turns SSE off. So always when you turn it back on in windows it will reset your computer. And that's why SSE turns back off when you restart the computer(because the mainboard detects problem and it switchs it off. Thats why you need a Bios update

Since the emulator runs fine for other users with ATI video cards SSE is not the problem. In your case, since the emulator shows the blue swirl and does not crash instantly it's not an SSE error. Try to change video card drivers (use even older drivers).

EDIT: I do not deny that the error may happen because of the program that enables SSE.

I know it works fine with other Ati users but if you have Ati+litle bit old mainboard with old bios, you may have this problem. The newest mainboards don't have the problem. And this A7A266 - E mainboard is a litle bit old !

Hi All, thanks for the advice and suggestions.

Managed to get it working now! It was an SSE problem. I looked on the ASUS website and it said that my motherboard should support it but it depends on my CPU.

But i flashed my bios and updated it (which i found scarey cos i've never done it before) and now it says that SSE is enabled!

Managed to run Shenmue and Resident Evil ok, a little slow down here and there, Ryo becomes a "ghost" sometimes as well, but i'm very impressed with Chankast's perfomance! i found that if i "underclocked" the dreamcast CPU the FPS was a lot higher, is that strange or normal?

Yeah my motherboard is old, but gonna wait till Athlon 64 CPU and motherboard prices drop and get one of those... Wonder if Chankast will work under 64bit conditions and 64bit Windows?

Thanks again!
:happy:

psyman is right, SSE are CPU instructions, nothing to see with GFX card, in the case you explained, it's seems that the program doesn't REALLY enable sse, it just change the sse state under windows, but it can't make the change for the cpu, only the motherboard allow the use of the specific sse cpu registers (and it's not the case for the one you described), and that's why the computer reset (due to a call to an instructions that the cpu doesn't recognize)... it's seems it's just a badly written piece of code, it shouldn't say the change is made if this program can't really make that...
