How to get Nextor Working

naeloob commented 5 years ago

Nextor is an advanced bios offered by KDL. Still not tested on secondary SD card, but i cannot make it works on VHD file, and i have not seen anyone report it works in any way.

Can you make it work?

Regards

I will look into that, been a little distracted by the NES and Genesis cores lately, but Nextor running would be nice.

Create a SDBIOS in your SD-CARD, the BIOS that goes with the firmware doesn't have Nextor Kernel. I've made a video that explains how to do it for SM-X/Zemmix Neo/OCM, my guess is that it might work for you as well...

I was finally able to get it to work, but it required updated NEXTOR BIOS.

Grab NEXTOR.SYS.

Then request a new BIOS from http://gnogni.altervista.org/

You'll need to use the "make.sdb.cmd" script to build the BIOS. I just took the default settings for each question.

Copy the newly generated OCM-BIOS.DAT and replace the existing one on your SD card or VHD.
Copy NEXTOR.SYS to the SD card or VHD, overwriting the one that's already there.
Copy the VHD to your MiSTer, or insert the SD card into the I/O board and boot the core. It should now give you the NEXTOR.SYS message.

NEXTOR.SYS version 2.11

followed by your usual AUTOEXEC boot messages.

To confirm this is working, try the drivers command. It should say

MegaFlashROM SCC+ SD v.1.3 on slot 3-2.
Type: device-based
Drives assigned at boot time: 2, from A: to B:

Also, it seems like the BIOS survives a reset, so I found the only way to actually test this was to power cycle the MiSTer. Make sure to do that before declaring your work "done".

Long MSX reset is hard reset with bios loading.

Yes, but it doesn’t seem, to work consistently, especially if the initial boot failed. And likewise, the “short” BIOS I found on the NEXTOR git will load on a reset, but no the first time. (I’m assuming this has to be concatenated with other files to work properly.)

So you need a power cycle to confirm that the new BIOS is complete and the system is not just working because of memory being left over from the previous run.

tompx411 this is indeed the way to go - try Nextor 2.10 instead - it works fine for me.
