Can I install am27h010 eprom into SPARCstation20?

Hello guys:

Can I install am27h010 eprom into SPARCstation20?

I am going to use OpenBoot 2.25r download from
http://public.planetmirror.com/pub/sun-bootroms/
I found the firmware is not large, so I think I can put it into am27h010.
The am27h010 is pulled from a SPARCstation 1000 system board.
The orignal eprom used by SPARCstation is a 27c240-20.

thanks for your help

Floppy experiment requested

I suspect I have found a bug in the floppy disc driver (fd.c, which can be  
viewed on www.opensolaris.org). However, it is possible that there is a  
hardware problem on my machine, so I am requesting people on this list to  
see if they can reproduce it.

I am using Solaris 10-u1 on an Ultra-2, but I would expect the same  
problem might exist on other platforms and on earlier OSes, since I doubt  
the fd driver has changed signficiantly in years.

Here is how to reproduce it.

1. Ensure that power management is on ("autopm enable" in /etc/power.conf)  
with a sensible timout, e.g. "system-threshold 900s" (or "15m").

2. Ensure that /vol/dev/*diskette* are emtpy. If not, 'eject fd' and wait  
15 minutes for pm to timeout. Volmgt should be running, of course.

3. Ensure that there is NO floppy in the drive, and that there has been no  
floppy activity for 15 minutes.

4. If you have Solaris 10, run (as root) 'dtrace -F -m fd' so that you can  
ensure that fd_pm_raise_power gets called during the next step.

5. Do 'volcheck -v /dev/diskette0'.

If it reports "/dev/diskette0 has media", then you have seen the bug,

It should, of course, have said "/dev/diskette0 has no media" and if,  
after seeing the bug, you do another eject and another volcheck (whilst  
the power is still up, of course), it will then get it right.

11 quid E450 not surprisingly wont boot..

I scored an E450 with 4GB 1x 400MHz and 20 drives on ebay for eleven  
pounds GBP. (now thats depreciation!)

Of course it doesnt boot (yet) - but it nearly does.

Id like to get it going rather than cannibalise it.. Plenty of cheap  
E450 parts on ebay means that theres no limit to what can be replaced..

I couldnt resist it - full of drives :-)

All Power is green, the key mechanism works.

OBP loads, I can see the hostid and Sun banner, It displays memory (it  
seems to think 2GB now) it gets as far as the initialising | which  
doesnt turn and it just hangs there forever.

I tried the diagnostic boot, same thing. I tried breaking into NVRAM  
and can get to an OK prompt and lots of drives show up :-) but from  
there on Im not sure.

I am planning to take all the memory out and boards and drives out and  
slowly rebuild it checking if it boots each time. That way I can  
isolate the defect.

Im sad to say I dont know a lot about this class of machine, being an  
Ultra 10 sort of person. If anyone has the time to send me links to  
places of interest or indeed immediatley knows the likely  
troubleshooting steps please feel free to email me directly and I will  
summarize.

That is cheap indeed.

Did you do the memory test routines from OBP?

Very nice score.

Have you tried "stop-n" to reset the ONP/NVRAM to defaults? I suspewct there may be some funky settings in
place from the previous owner, and this would help get the machine back.

Re: 11 quid E450 not surprisingly wont boot..

I've seen similar behavior in E450's before and it turned out to be a bug 
whose fix was supposed to come out with Solaris 10.  We never got to 
upgrading those machines while I was there, so I don't know.  But as I 
recall, the workaround is to turn off autoboot, power on, give all the 
drives plenty of time to spin up, make sure all the green lights are on 
and then boot.  Basically, the OS goes looking for disks faster than they 
are available to it.

Also, E450's are particularly picky about being properly grounded and 
having a fairly stable environment.  We had a problem with machine room 
humiddity control that led to major biannual shifts in humiity - there was 
about a 50% chance that any given E450 would crash in the week or two 
following the shift.  HVAC finally got on top of the humidity issue and 
boom - stable E450's.

Re: 11 quid E450 not surprisingly wont boot..


 >The methodology is the same, trust your instincts and use the  
force ;^)

I used the force with a VT terminal I keep in the garage. It turns out  
I think to be a system board issue.

I have SIMM Failures in each bank, and switching round the SIMMS makes  
no difference.

I also have two processors, both with DC converters, but only one  
'processor 3' (helpfully neither processor is labeled as such) boots.

My thoughts are I need a motherboard. I dont have any evidence that  
theres necessarily anything wrong with the memory, disks, processors,  
pci cards etc.

It counted lots of memory first time I booted it, now It wont get past  
the diagnostics.

Anyone agree with me its time to find a better main board?

thanks for all the positive emails.

Sparcs for pickup in Columbus OH

I'm posting this for a friend not on the list. He's moving and can't
take this loot with him.

This is in Dublin Ohio. a northwest suburb of Columbus.

> I have a bunch of old hp and Sun machine for some one who is willing to give it a home. Its a couple of sparc 2s a
sparc 10 and 3 sparc IPX. I also have some HP 9000 computers and Sun monitors.

Here is the craigslist listing in case you want to contact him.

http://columbus.craigslist.org/sys/610082365.html

If no one else takes them I might have to figure out some way to sneak
them into the house. :0

Hi Jeff

That has to be an ex-Lucent guy! Nobody has HP9000 gear at home for fun

Not true. I have one. But then I also have a Sun V880. Maybe I'm just 
nuts :-)
