Re: Linux on POWER5

Just wanted to say if you live in Pennsylvania or the surrounding states there are two Ebay sellers that let these 8203 boxes go for ridiculously low prices. They only offer freight shipping ($200-$300) or local pickup. I won't say what mine cost but they regularly go for around $100. Standard discl...

Re: Debian support remaining only for ppc64el

I was going to post about that. You had Debian running but when I checked their site they say only power8 was supported now. Suse support seems sketchy as you need to pay for updates? I thought maybe IBM maintained a distro but it appears not.

Re: Linux on POWER5

Hello there! I managed to install Linux on my POWER5, and even managed to use a Power Mac video card for better video performance. The key basic step for me was to separate /boot into an ext2 partition. I documented the whole process in a YouTube video if you need I can IM you the link. It works fl...

Re: Repairing Onyx2/Origin2000 Deskside Power Supplies

A lot of times the failure is because of something simple. Start by looking for anything physical, like a burned out part or bulged/leaking capacitor. Get a decent DMM and start checking passive parts like resistors an diodes. In circuit readings can vary but you'll spot one that is open circuit.

Re: TEZRO TOD CHIP INITIALIZING

japes, thanks for your detailed photos and experiments. I have fixed the problem and it was caused by my own doings. When I removed the old SNAPHAT it took out one of the press in sockets from the ST chip. I pressed the socket back in and installed the new SNAPHAT. It turns out the socket had a tiny...

Re: TEZRO TOD CHIP INITIALIZING

astouffer, are you saying the L1 time doesn't advance? ("l1 time always stays") or that the L1 controller has the correct and advancing time but the OS system time resets at every power loss? If the OS time is resetting you need a new SNAPHAT. The L1 time is kept on the DALLAS chip, the O...

Re: L1 USB Port Fuel

I seem to recall reading you needed special Linux software to do anything with that port.

Re: TEZRO TOD CHIP INITIALIZING

I checked it, and it´s Ok. I think the problem is that I don´t know how to reset the yellow chip, to power on. The chip is power off, and I don´t know how to initialize it. The yellow chip is just a lithium battery and crystal. It doesn't need initialized.I think this is for the l1. However I am ru...

Some drives have jumpers but this Seagate ST373207LC only has jumpers to manually set the ID. It's Sun branded drive for the record.

sash64 missing?

My copy of the 6.5.29 overlays doesn't seem to have sash64 in the root of the first cd. fx.64 is located in /stand where it should be but no sign of sash64. What is up with that?

Re: 80 to 68 pin SCSI adapter on Fuel

Alright here is the info. I believe this mod is only required on systems with a U160 bus like the Fuel. The Fuel expects differential mode but the pin on the adapter isn't connected. That means the drive is set for single ended (SE) mode. Making a simple voltage divider and pulling the pin high puts...

Re: 80 to 68 pin SCSI adapter on Fuel

After reading through the drive specs and poking around with my meter I have it working! When the interface “DIFFSNS” line is between -0.35 V and +0.5 V, the drive interface circuits operate singleended and up to and including 20 M transfers/s (Fast-20 or Ultra SCSI). When “DIFFSNS” is between +0.7 ...

80 to 68 pin SCSI adapter on Fuel

Does anyone have experience using one of those cheap SCSI adapters? I'm trying to get a Fuel to recognize a 73GB SCA drive but it never shows up in hinv or spins up. I tried an 18GB SCA drive with the same result. The cable seems to be alright because it sees a standard 68 pin drive. The specs for t...

Re: System failed pre-power check (Fuel) FIXED

Just wanted to say that replacing the yellow battery fixed the problem. It powers up just fine now. The l1 still has some weirdness. You can type "serial" and get command not found. Type a few other commands and then try "serial" again and it works. No typos or backspaces were pr...
