I didn't do a MD5 on the ISO, but I used the media check in the installer.
I had no errors during the install. I used the i586 installer, I’m using a via epia board. The cd just rebooted before using smei586 at the boot prompt.
To change the password I wrote " single" in the boot menu, after pressing a and then passwd.
I think it says "/bin/login: symbol lookup error" plus some more when trying to enter "admin" in the console, (really fast, then the screen is cleared and "server-name" login: returns).
I tried logging in to server-manager using both firefox and IE from a winXP box, using the username admin and the password I chose.
