Woohoo, found the right hack (as usually happens *after* I send mail :-) Since I couldn't get it to treat switch disks, I looked more closely at the image naming code (main.c, misc.c)...
On the same zip disk that I'd already put resc1440.bin on, I skipped over that to an easy-to-type offset, and dropped root.bin there: +% dd if=resc1440.bin of=/dev/sda +% dd if=root.bin of=/dev/sda seek=3000 1907+1 records in 1907+1 records out Then booted the zip disk boot: boot sd(0,5,0) Then at the silo prompt: boot: /linux initrd=sd(0,5,0)[3000-5000] root=/dev/ram (the root= may have been redundant...) and it worked! The installer is grinding through the badblocks check even as I type this. Anyway, if someone would like to turn this into English, it looks like we have a relatively easy "boot from zip disk" path to add to the install instructions... (I'd write it up more clearly myself, but it is 3am. Maybe later.) Wheeeeeeeeee! _Mark_ <[EMAIL PROTECTED]> The Herd of Kittens Debian Package Maintainer
