This is a machine build for Tandem by SGI and, based on the descriptions I have read, I believe it is a close cousin to the Challenge S.

Now I have spent a some time browsing the archives and I know this was a common problem some time ago on certain models of Indys. I can get the system to boot by replacing the Hard Hat vmlinux image with the vmlinux-indy-initrd-990313.gz image found in ftp.linux.sgi.com/pub/linux/mips/test. But that leaves me with a crippled RAM disk image and a root prompt. I can NFS mount my Hard Hat file system, but that doesn't help me run the installation. My question is: Can I get a precompiled vmlinux replacement for the Hard Hat distribution which will allow me to continue with the installation? Or, since Tandem is not officially supported, do I spend the next couple of months hand assembling a root partition on the machine from the bits I currently have working via NFS? Any advice anyone could give me would be greatly appreciated. Thanks.
