I was trying to install RedHat 6.1 for Sparc on a SPARKstation SLC over the network. The Sparc has not floppy or CD-ROM and only a 200MB scsi disk. An intel machine running RedHat 6.1 was configured manualy (tftptool didn't worked either). I have downloaded the tftp32.img file on the spark and booted the machine but, the screen goes crazy for a while and then I get the folowing message: Window Underflow ... and the machine halts. The machine can boot perfectly with vmlinux32 from the same distribution or with tftpboot.img from RH5.2/Sparc but there are not good for installation. Any suggestions?
How much RAM does the machine have?? It sounds like the machine is running out of RAM when trying to load the tftp image.
It is funny that you closed the report before my reply. The Sparc has 16 MBytes of memmory and from what I have read so far, that ammount of memmory is enough. Also I am not the only one with the same problem ... check bug #8006.
*** Bug 8006 has been marked as a duplicate of this bug. ***
I am also having this problem with a Sparc SLC diskless with 16MB RAM. The momentary delay between completing the tftp load (less than 1.5MB) and the wibbly screen suggests that the transfer has worked but the code is broken. Also I found that the error message had three 'W's at the start.
No one has ever posted any error messages for this problem. What are they?
There was an error message reported at the end of the second paragraph of the original report, namely : Window Underflow (or in my case WWWindow Underflow)
What version of the prom?
Prom version is 1.4 The exact text of the last line before the system hangs is : 130600 DDWWWindow UnderflowType b (boot), c (continue), or n (new command mode)
Why has this been closed? What action was taken to resolve this issue?
we were not able to reproduce the problem on the slc or elc here under 6.2. We're unable to take any further action to track down this bug.
But this bug was logged under RH6.1, not 6.2. Would be good for you guys to know what was wrong with that version of the SPARC release in case it happens again in the future. Oh well, it doesn't matter now anyway I suppose........
SPARC is not a currently supported architecture.
