I originally posted this in another thread but was asked to move it to its own thread for better visibility to for others with this issue. I'm having issues with my dev box. The GD-M doesn't show up at all, I went through and checked to make sure my SCSI card had the same settings in this thread. What could cause the GD-M to not show up? My unit seems to be stuck trying to emulate something, when it boots up uses a static Dreamcast logo not an animation and when it makes it to the Dreamcast menu it says it's checking the disk and hangs. There is nothing on the HDD when I connect it directly to the SCSI card. I did dump the two memory locations as suggested in the other thread The 2 MB bios (0x00000000 to 0x001FFFFF) & the 128 KB flash memory (0x00200000 to 0x0021FFFF), but I don't have anything to compare the dumps to. I tried to reflash everything that was available in dbflash, and I still get the same results.
