Thanks - will try it - grabbing.

I've read that! What I wanted to know is how to calculate the (what
looks like) binary data at the beginning of /etc/ld.so.cache. (And how
unLinuxy that is!)

Nonono you didn't read my post! I'm trying to do exactly what this
page suggests. ar still works, so I can get to the control & data
.tar.gz stage. But tar/gzip don't work. So I have to copy the .tar.gzs
onto my DOS partition, reboot into Windoze and unpack them with
WinZip. I can't then put the unpacked versions back on the DOS
partition cos the long filenames get mangled, and the rescue kernel
can't handle VFAT so I can't mount my Windoze partition. So I have to
burn them onto a CD. This procedure is a pain in the butt, and a Win98
app that understands ar format would cut out a reboot or two.

However, the rest of that page had some useful stuff on it, so thanks!
