Two issues:
1 - When creating the installation media, I no longer have a clear screen during the installation boot.
2 - When I install from previous Yosemite media with older clover/config.plist, and upgrade to El Capitan, the HP Probook Installer Clover Edition 6.4.3 complains that I did not press F4, even though I definitely did.
Details:
Installing on my zbook15g2. When I copy the 4400-4600 config.plist to the USB install media, and I boot from the usb key, my screen is garbled, however the cursor is not. I have not had a problem in the past installing with previous config.plist.
As a science experiment, I took my older 10.10.4 install usb, and re-installed from scratch applying the HP Probook Installer Clover Edition 6.4.3. I then updated to 10.10.5 and then to El Capitan. Note, that when the zbook15g2 booted to the El Capitan upgrade media, the screen was garbled during the upgrade process. Once the upgrade completed and rebooted again, the screen was clear/normal.
I rebooted into clover, pressed F4, and saw the disk light have activity. When I ran HP Probook Installer Clover Edition 6.4.3, I got the warning dialog that F4 had not been pressed, and the install error'd out. I rebooted and repeated again, and same error.
Thoughts?
