This ISO I made aims doctors. So I took Gnome Zen Mini and added couple of programs and also openEMR.
The reason of choosing Gnome Zen Mini was the low requirements and also the basic system installed.
The programs I choose to add (please tell me if those are enough):

Keep backup

deja dup
gnomebaker

Graphics

gimp
inkscape

Remote management

teamviewer

Video

vlc

pdf viewers

evince
pdfedit

Tools to install openEMR

mysql-administrator
mysql-gui-tools

To test LiveCD, run Firefox or Chromium. It will open a DEMO environment (you need Internet). You can check how the program works. There's a DEMO that the patient can see his visits.
USER-PASS for DEMO are:

Administrator: admin - pass
Physician(more permissions than clinician): physician - physician
Clinician(less permissions than physician)" clinician - clinician
Accountant: accountant - accountant
Information desk: receptionist - receptionist

Pass for patients DEMO:

Susan1 - susan
Phil2 - phil

Because of permissions of LiveCD, you must install LiveCD to use openEMR.
PASSWORDS for installed openEMR are:

User: medical - medical

Now if you want to install PCLinuxOS Medical go to PCLOS Menu Button -> More Apllications -> Configuration -> Install PCLinuxOS Medical and follow the installation instructions.
USER-PASS are:

Root: root - root
User: medical - medical

After the installation you'll have a user medical.
