- E475: In this episode i install the BFG9060, a 68060 cpu w ram board into the Amiga 3000d. there has been a ongoing issue with its dma and scsi access with the internal scsi of the 3000 series machines. so i start to figure out just what exactly causes this and how to work around it and enjoy a 68060 BFG amiga 3000. from swapping in a 4091, to finally figuring out the internal issue on internal scsi of this card. Hope this helps you. enjoy!

Chris you made my day; not because you have the ultimate solution, but seeing someone else fighting with the same bullshit, just feels good... ;-p
Back reason is sadly that the SCSI and DMA on the A3000 is STUPID picky with its timings. breaking on some 060 solutions..
get a board work on the 3000 SCSI DMA. and it will work on anything. this is why we do most of the TF4060 tests now on A3000 and AA3000..
I hope you can get the TF4060 to work with A3000 SCSI. My Cyberstorm MK2 and MK3 work totally fine in my 3000's using the A3000 SCSI. I also had trouble with the BFG so I gave up on it and put it in my 4000.
Thank you Chris, you do all the all the hard work so we don`t have too ! it really is appreciated dude
like the old scrubbing bubbles commercials!
Pre-Gotek, in running my AV production studio in the Chicagoland area, I had to make sure all my A2000 systems were rocksolid, so I used an external SCSI Syquest and built cartridges for it that would have a base Amiga OS, and one for each system as I slooowly built them up to ensure that all the apps weren't glitchy, didn't freeze or guru, especially when migrating to later expansion cards like from the 040 to 060, rom v2.04 to v3.1, updated card firmware roms, etc. It saved me numerous times and kept me in business with no downtime. As an added bonus, it allowed me to change entire system configurations on the fly by booting with a cartridge geared specifically for only graphic arts or only audio editing or only business productivity etc.
Wondering if my A3660 card was messing with board scsi on my own flaky A3K- as I didn’t terminate the Zulu board either. Nah, it was flaky before the Zulu!
This is a great diagnostic session as it’s clear the BFG has some issues with same. Andrew is a great resource for Amiga users!!
You mean me? Thanks :)
@@linuxjedivideo yes Sire! You greatly aided my 68030-TK2 accel board journey. That and the romulator too. Your blogs are entertaining as well, up there with Lyonsden and Chris Edwards for technical savvy
Fascinating video. Looking forward to the deeper dive!
I got a Zuluscsi RP2040 and had similar issues with my Cyberstorm/060 MK3. There was a firmware update for it last month and that fixed the issues I was having. (Firmware I installed was 2024.02.06)
Nice troubleshooting, Chris. It amazes me how fast the system boots with the 060 and ZuluSCSI. Love how backing up the system is super easy.
Great app Mr. Hooper!
I never got my BFG to work properly in my 3000D with Buster 11 and DMA mod. Got fed up and installed a WarpEngine 040.
ZipTest will also tell you if the ZIP chips are Static Column Mode or just cheap Fast Page chips (slower). It is shown as one of the first lines of output. Most SC Chips for sale on the Internet are actually re-printed FP chips and sold as the faster, more expensive SC variant. All from China.
This tool, ziptest, only works on the A3000 and tests the ZIP chips by bypassing the OS and going directly into the hardware. It will show a text-graphical presentation of all the RAM banks, their ID's and if the chips are good or not. It also does a thorough low-level test. It's a really good tool.
GREAT video man!
That Zulu and 3D printed mount look excellent

This is great. Thanks so much. I’ll give it a try. I have a very similar setup w/a A3660. Omg so frustrating
I had all kinds of issues with the TF1260 once I installed the mmulibs. That error @18:35 was a large bane. For some reason the 030 doesn't care at all about what mmu libs are installed but the 040 libs causes a conflict with the 060 chip. Once I removed the 040 libs and kept the 060 libs Everything just worked.
Nice Detective work Dr Chris 👍🏻 Have had many an issue with the MMULibs on other accelerators. MK1 Cyberstorm with a REV 1 and REV 5 full fat 060’s would also guru and get lockups. I always run MMULibs in “Expert” mode. That way you get to pick and choose what gets installed. I use the SetPatch setting to help choose CPU. You can then switch and play with which MMU functionality you want to use. Or all of them off and just have CPU Libs on. Worth trying that way. Also have had issue with the Apollo Cards (Classic ones, NOT vampire). 1240 and 4040 will not play nice even when having the correct configuration in Env-arch. Look forward to what you find next. Cheers 🍻
Interesting that MMU libs adds problems - same experience here. (I’m sure you used 030 version for the 060 LC). FastIEEE failing was the bane of my 3000 until removing it!
man, if I had to try to figure that out, I would have less hair then you!LOL
Wow Chris, that is quite a zippy machine, even if it is a PITA to get running. I would have loved such a zippy machine when they were new 30+ years ago. That said, now I'd rather use my 500+ once I get my RGB2HDMI installed along with the pistorm. Add an A314, and that's 3 pieces of Pi in my Amiga. The only thing that config lacks is fast Chip RAM speed.
yeah it boots super fast, any amiga without a RTG card will boot super fast.. this was just a identification issue, and now its rock solid without the mu files in sys:c and does what i need it to do.
16:05 "Call of Duty" :D
Nice video thanks! Did you try adjusting the MMU-Configuration file for the BFG? There are instructions on the Github.
no i just wanted to do a base install and work my way forward, thats why i did it twice after the working one to purposely break it. it has been solid as a rock since not using the mu files in the sys:c dir, it DOES have the 060 cpu library working fine as sysinfo reports the 060, the official word is that it is timings in the Super Dmac02, and to find the unicorn super Dmac04, but those are beyond impossible to find. I will work through the docs to see if i can reign it in, i have asked others, including WranglerUK and GadgetUK and they are discussing various situations.
Messaged Chucky about the BFG9060 in A3000 and he thinks the DMAC is part of the problem, you need a rev 04 (and because of that a Ramsey 07) to get it to work flawless. Those are extremely rare, pretty much impossible to get. Unless you happen to have a borked A3000T that has one. He (of course) has one in his AA3000+ and it apparently just works.
[edit] And if I misunderstood anything it is of course my fault and not chuckys 🙂
no one has Super Dmac04,
I did have a lot of problems with Hyperion's MMULibs too, hence why I blogged about using the Aminet ones. Not sure why you are having these issues, as the setup is incredibly similar to mine.
Actually the two differences: I don't have a Buster 11, and my 060 is an R5. Not sure if either make a difference.
@@linuxjedivideo ^this is my setup on the A3K, and trying to go with 030 no fpu mmulibs by hyperion is a mess (install file errors), with an A3660. fastIEEE is a nightmare....only Amiga makes it possible!
I wonder if the MMU stuff needs to exclude a range here - something related to DMA range perhaps... I found similar crazy glitch issues on a 4000 with MMUlibs recently!
im sure it does, i was just trying to figure out what it was, or a possible what it was. is it the Defacto fix? no, but it works for me with what i use if for,. I know deep inside it is timing on the SuperDmac-02, but no one has any SuperDmac 04's for sale and when they do they are the price of a mini
@@ChrisEdwardsRestoration The A4000T has no Dmac and i get the EXACT same issues that you get in that video.
Will peel out my spare scsi2sd v6 I bought for my A3KD years ago and experienced the same issues with A3660 running @66MHz and see how it goes without MMULibs.
A long fight with this Amiga.
just to identify it, im glad i went through the trouble to figure out what is giving me trouble, now shes rock solid and works great!
Nothing to do with the DMA mask in HDToolbox? try to change the value i think you can google other values, I had sam problem with a GVP 030 Combo card in my A2000 i had to change the DMA mask value en then it worked.
So MMULibs is a problem with the BFG9060? As you instructed, I'm weeding out MMUlibs from my A3660 LC60 and its already tedious. Does the A3640 have these MMUlibs issues on the A3K??
No only the newer bfg and the tf4060. And 3660. However the tf4060 has some new fixes in its firmware
@@ChrisEdwardsRestoration think Alen Marks will be making the TF4060 soon?
@drphilxr i think he already is
Chris, just curious--were you using the "MuLib aware experimental 68060 library" (Mu68060_Ex) by Thomas Richter? I assume you were, but just wanted to check?
i tried both the hyperion built in and the 060 ones from thomas, no change, just worse. so if i deleted the mu files from sys:/c it was fine
Hey Chris. I've been having a real horrorshow with the built-in SCSI in my A4000T with 3.2 and a BFG9060. It's basically a 4091 isn't it?
Excited to try installing from scratch and leaving the MMUlibs out and seeing what happens!
Update: works fine without MMUlibs. But I think I need MMUlibs to get the best out of the card. Absolute nightmare.
Yeah but still works at leasy
@@ChrisEdwardsRestoration The SCSI hard disk works ok with MMUlibs, but accessing the SCSI CD drive makes the Amiga hang after a few seconds. Very strange. What can I try?
Hi Chris & All, I installed a BFG9060 with 060 rev. 6 and installed the suggested MMU libraries. I have noticed since installing the card that every time my Amiga generates a disk click to the floppies that I now get a brief flash on my monitor (Dell U2410f). I never had this issue before installing the card & CPU. I’m going to try noclick and see if that helps, but this is a weird issue.
Heck with no click, I would delete the files out of the C directory like I did it makes a world of difference and it functions flawlessly
@@ChrisEdwardsRestoration I’ve never heard about that. I’ll definitely check it out. Thanks!
@@ChrisEdwardsRestoration Hi Chris, what files would I need to delete out of the “C” directory to remove the clicking? Thanks!
did you watch the video, i explained it all in there. anything starting with
MU on it
do u know how to program the Amiga or Amithlon ?? thanks........... i mean 68000 68010 or 68020 and pentium chips too? thanks.............
wait what?
Have you tried a different CPU? Maybe the MMU is knackered?
Its a known problem w the bfg
Any 68040 or 68060 should have a suitable library to enjoy in full. You can try C=(040 only(?)), P5, GVP(and descendants) and MMUlib.
i am running the 060 libs, hence why sysinfo reported the 060 as did the cli command
Chris, I would not be too worried about the 3.2.2 as apparently Hyperion are bringing out AOS 3.3 this year.
yes I know. but who knows if it will address the issue.
Chet! Ahh $hit :)
