Question NVRAM Checksum Issue
Posted by: CB_HK - 10-15-2018, 03:56 AM - Forum: Hardware/Triage/Repair - Replies (2)

I decided to set up a serial console with my Crimson to poke around a bit and see how things were going. The real goal was to make sure my console setup was working correctly before I attempted to hook up to a VGXT board set and make sure it's operating correctly. While the VGXT passed all of its power-on tests, I noticed that the Crimson was outputting an NVRAM error to the serial console but not to the main display.

Any thoughts on what the issue might be? I attempted to fix the issue with the Command Monitor but no luck yet.

Code:
Non-volatile RAM checksum is incorrect:
Initializing the non-volatile RAM parameters.
From the Command Monitor, check with printenv and fix with 'setenv ENV_VAR'
where ENV-VAR is a non-volatile environment variable such as bootmode.

  Old HDD licenses
Posted by: blacksmith - 10-14-2018, 07:22 PM - Forum: IRIX/Software - Replies (3)

I've got 2 SGIs from a nearby University and on both of them there are various software licenses. How can I preserve them in case I want to upgrade the HDDs.

  Missing sash
Posted by: ha0124 - 10-14-2018, 03:47 PM - Forum: IRIX/Software - Replies (2)

I've just installed Irix 6.5 and then the overlay to 6.5.11 on to a blank disk on an Origin 2000 system, but for some reason even following the online instructions it seems to not put sash in the room of the OS drive. Everything else is there, but I just cant boot off the HDD.

I'm guessing I'm missing something, but can't figure out what!

  Porting of C= related software to SGI
Posted by: Trantor - 10-14-2018, 12:40 PM - Forum: Development/Porting - Replies (1)

I have finished setting-up a simple development environment with my Indigo2 (nfs shares, telnet server, bash basic configuration, vim and some other tweaks) in order to start doing some software ports. Since I'm mainly involved in C= related projects, I've told myself: "why not going retro also for retro devel tools"?  Big Grin
I've started with something really easy, pretty much like a simple recompilation. The software is named TapClean, which is well known by people who try to preserve tapes from the old C=64 (I've also used it a lot of times with my tapes collection). It turned out to be a software written in C very well... but is also slow as a hell in analyzing and "cleaning" the tapes. Here is a stripped output of a "cleaning" run of a .tap file created by me...

Code:
trantor [ ~/irixnfs/tapclean/src ]$ time ./tapclean -o 0208\ -\ tcgames4a.tap

TAPClean 0.38-pre-16 - (C)2006-2018 TC Team
Irix Version 1.0.0
[Built Oct 14 2018 by Trantor/HokutoForce]

It took nearly 40 minutes to clean the .tap on my Indigo2 vs 52 seconds on my i7 macbook pro 2015  Big Grin Big Grin
Clearly this tool is nearly unusable on SGI, but for the sake of completeness (or benchmarking Tongue ), if anybody wants to download the attachment, try it with this command:
Code:
time ./tapclean -o 0208\ -\ tcgames4a.tap

and paste its system cpu and the last three rows with real/user/sys time, it can give me and idea on how different cpus perform vs my IP22 [email protected] teal indigo.

Question Repair loud bearing/jet-engine whine from old HD?
Posted by: amatecha - 10-14-2018, 05:57 AM - Forum: Hardware/Triage/Repair - Replies (4)

It was surprisingly hard to find real concrete information about this online, searching via Google (other than typical "did you try [totally irrelevant troubleshooting step]").

The old HD I'm using in my O2 is _very loud_.  The typical loud whining noise from old drives that I've heard described as "failing bearings".  Is this something a person could reasonably resolve/repair themselves?  I do most hardware repair myself, including replacing PCB components (as long as someone has identified the proper one to replace -- I am no electrical engineer haha)...  Any helpful info anyone could share on this would be appreciated.  Somehow I just can't find definitive info regarding what is physically causing the sound, other than occasional comments about failing bearings.  Not much for me to go on!

Guess my alternative solution is to see if there are ultra wide SCSI adapters I could use with a scsi2sd device Wink

  Octane power on music?
Posted by: Infiltratr - 10-13-2018, 03:37 AM - Forum: Hardware/Triage/Repair - Replies (4)

Are octanes meant to play power on music?  All of mine seem fine in Irix, playing sound and everything through the monitors' speakers but I have never heard any power on music?

After years of dicking around I finally bit the bullet and bought that cheaper one without a hard drive on eBay. Kind of a roll of the dice but we'll see when it gets here in about 10 days. Hopefully beyond the missing hard drive there won't be too much it needs.
(fingers crossed)

It appears that the IRIS Crimson in the movie was actually an Onyx in disguise!
