No GD-ROM, Can't read MBR from IDE by LBA - polyfusion - 30.04.2016 12:18 Trying to get this to work, hoping someone can provide some guidance... Have a XCKDIY board with a 2.5 HDD mounted onto it. It has an oscillator (and a resistor) already attached. The Dreamcast has the "boot_loader_unlock_G1_IGR_dbs_nogdrom.bios" flashed, and I believe it's ok, as I get the DEV bootscreen, and Dreamshell then loads ok from the SD card. However, in the bootup screen, I can see the message: Checking for G1 ATA devices... Can't read MBR from IDE by LBA Then some messages relating to the loading of the SD card, which it then does sucessfully. When I go into ISO loader, the HDD isn't available to select. The HDD was formatted in FAT32, and I have a DS folder loaded to the root of the HDD. I put the megavolt85 "DS_CORE.BIN" file on the root of the DS folder, and removed other BIN files from the root. I think I followed the same as pstationBG in this thread: http://www.dc-swat.ru/forum/printthread.php?tid=2250 Anything else I should try? Thanks. RE: No GD-ROM, Can't read MBR from IDE by LBA - polyfusion - 30.04.2016 15:42 I got it working, I was looking at some photos of HDD's people were using in their DCs, and could just about make out that they were jumpered. So I put a jumper on the two pins that looked like it needed it, and it works great now. Also, I see 3 solder points which look like they are in the right location for the DCs lid switch. Had anyone installed a switch, and advantage/disadvantage to doing so? Many thanks to everyone who made this happen.

I just dusted off my XCKDIY HDD adapter and I remember last time I tested it that I never got I working (with a known working drive pulled from my soldered G1-ATA SATA mod). It halted on the init-screen for G1-ATA and SD devices. What pins did you add a jumper between? Thanks a lot for your answer! |
