openbsd yesterday, i needed to install new os to my amd64 box. alas, my bro borrowed my dvd rom and i didn't feel like installing from floppies (mine are all dusty) i have 256mb flash disk lying around, then i googled how to boot openbsd from flash it turned out that the flash disk must be skipped by 32 sectors, have partition sd0a for boot and sd0i for MSDOS (so ubuntu and osx can mount it as normal flash disk) after that, the pc booted successfuly from flash disk. untar all tgz from sd0i the whole openbsd45 fits in 256 mb flash disk :d now i don't need to burn blank dvdrw everytime there's new release it's quite educational for me since i've been spoiled by always installing openbsd solely from cd (easiest) or floppy+ftp (trickier, for older system like thinkpad x360d no less) it's lightweight, with dwm. firefox3 with dozens of tabs+addons, vncviewer, xterms, inkscape open take like 200+mb. my 1GB ram is not exhausted yet, my 2GB swap isn't even used at all. similar setup would exhaust my ubuntu (i migrate back from ubuntu to openbsd and osx)
