IDE Mod Reset Issue [SOLVED]

[pcwzrd13]

I'm having a strange issue with my IDE modded Dreamcast. On rare occasions, the screen will go black (no video signal) in the middle of playing a game and after 10 seconds or so, it will reset. This has happened on the DreamShell menu a couple times as well. I should also note that sometimes it will not fully reset and just goes to a black screen; when this happens I have to turn it off and on again a few times to get it to boot up. It's strange because sometimes I can go months without it happening. At first I thought it might have been the common random reset issue that others have had but that doesn't appear to be the case. I've tried all of the known fixes for the random reset but nothing worked. Has anyone else experienced this with the IDE mod? Is it possibly an issue with DreamShell or the DreamShell bootloader BIOS? I might completely resolder everything but I want to know if this is possibly a software issue before I do that.

Here's my setup:

- NTSC-U Dreamcast VA1
- DreamShell bootloader flashed to BIOS chip
- 2.5" IDE HDD with cable soldered directly to the underside of the motherboard
- Hard drive is internal
- GD-ROM board connected with laser assembly removed to make room for HDD
- DreamShell GitHub version

Update: The issue appears to be fixed now. The problem was with the BIOS chip not being soldered well enough. I resoldered all the legs and now the reset issue appears to be gone.
