I am really undecided about eCS 2.2, and the way that it installs. I managed to get the first version of the eSC 2.2 install CD ISO, just before it was replaced by what appears to be an older version (not sure what that is all about, I wish I had not erased the first download). The first version did a pretty decent install into VBox (latest) under Win7. However, since it was, apparently, an incorrect installer, USB wouldn't work in VBox, and I decided to change some options, I tried the second ISO. Five times, and I still couldn't get it to install properly. I use the ISO in VBox, and it does check out okay.
One of the problems was that I missed turning off the RPM/YUM junk (well hidden, in a not so obvious place). The installer crapped out in the middle of phase 2, because it couldn't install ODIN.
Another problem, is that I set up VBox for two processors, and enabled the options that work with ACPI (works in eCS 2.1 in the exact same virtual machine). The installer would not recognize the two processors, and it would not install ACPI, even when I changed to Modern, with ACPI, instead of Virtual Machine.
Then, I changed VBox to use SATA/AHCI controllers. The pre-boot stuff worked okay, but eCS stopped shortly after the logo went away. More work to do with that configuration.
So, back to the old default setup. ECS installed, without ACPI, without SMP, and it somehow identified the virtual Intel gigabit NIC as an IBM NIC. Even eCS 2.1 got that right.
Okay. On to the real machines.
First attempt was on an old machine. I can't get that thing to read the DVD (not sure why, it was working). Abandoned that, for now.
Okay, try the Lenovo ThinkPad L530. First, there is a bad version of the USBEHCD.SYS driver, that won't work with USB mouses (at least on the two machines that I have that use that configuration). I am now looking at a "Press Enter to continue..." message, because Uniaud failed to load. This sort of works in eCS 2.1, but I need to use the later version of Uniaud, or it won't load (doesn't work properly anyway). Pressing Enter does nothing. Ctrl-Alt-Del does nothing. I guess it is power off, and start again, leaving sound out of it, but not today, I have other things that need to be done...
