30 april 1993: the free and open WWW started…

Posted by jpluimers on 2013/05/03

This year, the Dutch Queens day this year had a special nature. On the nation level: the abdication by former Queen, now Princess Beatrix, and the succession and inauguration of King Willem-Alexander. On the marching band level: Adest Musica had their Dutch premiere of the new show Mother Earth which will be their entry during the quadrennial Word Music Concours this summer. On the personal level, my best friend visiting The Netherlands for just a few days, so finally a chance to catch up in person.

So I totally missed another important historic event: the 20th birthday of the releasing the WWW source code in the public domain.

Screenshots: Creating vSphere 5 ESXi embedded USB Stick with MBR partition table

Posted by jpluimers on 2013/05/03

A long time ago, I promised steps how to install VMware 5 ESXi using the MBR boot format.

The steps with screenshots are below, but first some background information.

As of VMware ESXi 5, GPT (short for GUID partition table) is the default partition table used by VMware ESXi.

Disks smaller than 2 TB can boot with MBR, but GPT It is a requirement for disks bigger than 2 TB. GPT also needs a UEFI compatible  BIOS.

Some older BIOSes (like those of my HP XW6600 machines: still running strong after many years of fine service) do not support GPT.

Luckily, weasel (the open source Operating System Installer that VMware ESXi uses) can be forced to use MBR using runweasel formatwithmbr.

Forcing MBR is a 2-step process.

  1. Get to the boot prompt: press Shift+O when the progress bar appears
  2. Running weasel with the MBR option: after the “runweasel”, type a space, then formatwithmbr

Below are the screenshots of a VMware ESXi 5.0.0 installation I did this way.

But it works equally well in ESXi 5.1.x

After writing this post, I found out about ESXi 5 Won’t Boot From USB which solves this exact problem for an HP XW8600 configuration (those are slightly larger machines than the XW6600 I have, but the architecture is the same).
