It was sometime ago and it may no longer be there - the image on that site now mentions Sparc 2.6, I guess 2.4 has been removed.
I have no means for you to take a copy of my image.

It may take me a bit of time to get around to it, but I will do so as soon as I can. > You can grab the code like this: > git clone -b scsi_assert git://repo.or.cz/qemu/stefanha.git > -Nigel -- Sparc guest assert error https://bugs.launchpad.net/bugs/671831 You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. Status in QEMU: New Bug description: The latest version in git (d33ea50a958b2e050d2b28e5f17e3b55e91c6d74) crashes with an assert error when booting a Sparc/Linux guest. The last time I tried it (about a week ago) it worked fine. Yesterdai, I did a git pull, make clean, reran configure and compiled.
