Re: [Hardware issue] G5 (PowerMac11,2 DC 2.3, air cooled) random hangs
Hello! I suggest the G-Group from Low-End-Mac (LEM) for this. Subscribe to the G3-5-Group and ask your question there. https://lowendmac.com/lists/g-list.shtml (Since it might be down – I cannot see this page currently – you could check the Internet Archive to see what was in there: https://web.archive.org/web/20110227220734/https://lowendmac.com/lists/g-list.shtml) Just so much: you probably want to check the PRAM battery and replace it. https://www.ifixit.com/Answers/View/15881/G5+powers+on%2C+fans+run+at+high+speed%2C+nothing+else. I think I had this on a couple of PCs and Macs. Most of them just loose the BIOS settings in the CMOS and the current time from the RTC, but some act up. I had a desktop PC and a notebook that wouldn't boot. My Power Mac G5 had the roaring fans, but would boot eventually (every second time or so, with fans unconditionally roaring up). Power Macs in particular seem to act very very strangly when the PRAM battery is empty... Good luck!

Re: hardware donation
Sure. The machine is a 15 inch powerbook G4 with high-res display and 1GB of memory (if I remembered correctly). I swapped the original HDD out with a SSD in (32GB). But the SSD is not very fast in writes as I later found out. I also took the internal CDROM out to reduce the weight but the CDROM is otherwise just sitting there collecting dust. If you guys need it, please let me know. It would be nice if I don't have to ship it and just give it to someone locally. (I am in SF bay area). :-) Cheers!

(Griffin PnP is one). is fast enough the 233-300 mhz for web browsing no problems there. i use a 250g3 laptop every day. yesterday i build upstream of embedded common lisp on my g3 for testing/ comparison to debian package (something wrong with my etch version). Brian p.s. it is noted that old world mac is easy to have runnning several versions of linux and be testing them and switch back and forth. bootx is more flexible that way than yaboot. also easy to clone a copy and boot it if you like to experiment with sid or another distro. beats an old imac in my book any day ... -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

I came back, put it on a desk and problems showed up - it made some sounds like usually when waking up and then nothing - blank screen, no reaction for mouse, keyboard, so on. I rebooted it (command+control+power) and MAC OS X booted also without anything on screen. I know it was OS X because when harddrive was no longer working I pressed power and then enter and computer turned off after some seconds. Then after couple of reboots friendly OpenFirmware screen showed up and I was able to boot linux. Now I don't know if it is hardware or software problem. My first impression was it is strictly hardware (motherboard?), but then I started thinking - why is OS X starting (linux is my default os)? Today the same happened. I cannot replicate procedure to finally solve problem, but the problem occurs when I take the computer with me when I go to university. Maybe some shock problems (but I use special Kensington notebook backpack)? I would really appreciate if some of you could say anything more - if this is motherboard problem I have 9 days of warranty for it (it was replaced last year in June 2003), if it is anything other piece of hardware that probably means a lot of money to spend (Apple computers are very expensive in my country - the cheapes iBook G4 1GHz is 1600$ which is american price for the cheapest PowerBook G4 1,33GHz) - warranty expired.

Ok, well, I'll investigate when I have such new HW at hand (soon hopefully). Just to scare you, straight from the M48T59 documentation: Calibration occurs within a 64 minute cycle. The first 62 minutes in the cycle may, once per minute, have one second either shortened by 128 or lengthened by 256 oscillator cycles. If a binary '1' is loaded into the register, only the first 2 minutes in the 64 minute cycle will be modified; if a binary 6 is loaded, the first 12 will be affected, and so on. Taking into account that the oscillator is 32768 Hz, 256 more cycles represent 1 part in 128. Almost 1% if you happen to calibrate on the wrong second! Of course we could try to calibrate on 3 seconds and take a majority vote, but I don't like losing so much time at boot for a stupid hardware bug^Wfeature. On my VME boards, I have been careful to clear the adjustment register when I got them (you can set its value with a simple firmware command). Gabriel.
