Trouble booting from ssd

[ArturRGT]

Hello again. This is the second system i modded. The first one works perfectly. This one is giving me some trouble. Everytime i put the boot loader disk in the cd drive it gives me this screen, which i know is not normal:


Sometimes it gives this same screen but without the weird dots. And sometimes it boots into dreamshell and allows me to play normally! I would say it boots me into dreamshell in about 1 in 10 times. Otherwise it goes to a black screen after showing this.

This is my current setup:


Does anyone know the issue or have seen this before?
Thank you!

Thank you! Use an 80-way ide cable that solves this problem.

And just ground the extra 40 wires, right? I wonder why this does not happen in my other dreamcast which is modded exactly the same way as i did on this one. What exactly is the issue? Wires interfering one on another?

Also i found out that the dots appear when the console stayed turned off for a long time. Then i reboot it over and over, and every time less dots appear, until it eventually boots. After this, it boots to dreamshell every time i reboot as long as it is still "warm". If it stays too long turned off i have to repeat the process.

I have soldered a ceramic capacitor between points 1 and 2 of my ide to sata adapter, so maybe that's what is causing the issue (i did this in the other dreamcast i have because it wouldn't boot otherwise, so i did it on this one too just for precaution). Could it be defective? I'm not an electronics expert so i don't really know.

The only difference between the two dreamcasts i have is that this one is a VA0 and the other one is a VA1. Does this make a difference?

The other one is not currently with me though, so i'm not able to troubleshoot.

I have simply not connect pin 1.

I don't thing so except if you have change the bios, there are not the same I believe.


Have you try some visual concept games with this SATA 2 IDE adapter please ?
I don't use the same as you may have better result.
