well, i got gentoo running on an ultrasparc 10 :)

yuu-huu!

very important: make sure the kernel is compiled correctly, it must support the hard disk controller you're using (look in /var/log/messages to find this) and also framebuffer support has moved in menuconfig for 2.6.17 (or the documentation is quite confusing here). if you don't activate it in the kernel, you won't be able to see anything when you reboot :)

now i've just written a short program in c to check how fast the computer is (the bogomips is none too encouraging).
basically the program finds the xth prime number. i've found a 440MHz ultra 10 is about a quarter as fast as a 700MHz pentium III, so i'm probably doing something wrong here. are there some options for gcc one should use? i tried the typical -O3 but it didn't have any noticeable effect (pretty much what you'd expect for a program of this complexity). although i don't intend to use an ultrasparc 10 for number crunching, any hints would be welcome.

(strangely, the pentium III is faster than my athlon 64)

Well Sparc is a special CPU like my Alpha. Good on som operations bad at orhers. my Alpha EV56 500Mhz is very slow on interger. probebly my K6-2 400mzh is equaly fast but floting points my Alpha is as fast as a P3 1Ghz in SuperPi benchmark for instans.

But Sparc what I know and I hade the opertunity to bench on in compiling once agens my former workstation whit dual 1.8@1.95Ghz Opterons VS I think it was 2 or 4 800mzh Sparc IIIi CPUs and well I culd have compiled the same app 3-4 times over before thay where even close to finish. Think I did it under 40 sek and thay tock like 2-3 min or so.

So not very fast no but still thay are probebly good at sertent tasks but havent realy look in to the Sparc computers that mutch.

gentoo worked great :) even the Xserver worked a charm :)

so i deleted it and tried to install open solaris (one loves a challenge, and the lack of an internet connection makes gentoo quite long-winded (the ping when using apt-get is about 2 and a half hours in sneaker net)).

anyway, i have a question to this opensolaris thing. i know this has very little to do with gentoo, but the regulars at sonnenblen.de haven't been able to help me, as it's sort of half-GNUlinux / half-sun.

when i try to install open-solaris, the installation programm stops and throws me back to a shell (ksh) saying that there isn't a hard-drive installed, or that it isn't correctly formatted. solaris has the program 'format' in /sbin to deal with cases like this. so i try to format the hard drive (which it can find under the catchy name c0t0d0), but the program refuses to format the drive, saying it is still in use. /etc/mnttab (/etc/mtab for open solaris) doesn't agree with this assertion.

now i can format the harddrive with no difficulties using fdisk under GNU/linux, but the formatting is not recognised by solaris (despite sun partition and label).

the question is, does anyone know what's going wrong? the people at sonnenblen.de mentioned something about my obp being too old, which i suppose is possible. the trouble is, when i got the computer, i installed open solaris on it without a problem (and then deleted it because i didn't have a mouse and i wanted to try out gentoo). am i over looking something basic here?

any suggestions are very welcome

howie

------edit------

sometimes the whole world seems to conspire against me. the problem is the ide controller which doesn't like this drive. i just swapped in an old ide i happened to have lying around, and the installation worked a charm. however i am not impressed with solaris 10, so i'll install gentoo again (solaris 10 doesn't seem to come with a c compiler! please someone tell me that i've overlooked something...)
