Still stops after RTC century offset, even in Safe Mode.
Ok, let's do a quick resume.
You have downloaded
http://www.icarosdesktop.com/icarosfiles/IcarosLight_2_3_0_usb.zip , unzipped that file, then used passmark imageusb to create the pendrive ?
Then you inserted that pendrive into your machine on a USB header that has no other peripheral's attached (also not internally) and booted your machine. You entered the grub menu and selected to start icaros in safe mode and you watched the boot process continue on your VGA attached monitor (*), and the last part that you are able to see is "RTC century offset" ?
Did you disable all your internal/external connected devices in your BIOS, and changed your boot priority ? How does your MCP7a handle the floppy options in the BIOS ? (that was the only weird things that did not made any sense to me as the board does not even seem to have a header for a floppy-drive (but perhaps i overlooked it ?). If possible disable that obscure device, unless it tells somewhere that it allows your USB connected device to act as a floppy drive (in which case more testing is required simply because i do not know your board).
(*) it can be that video is outputted (e.g. switched during boot-process) on another output connector.
In one of your previous post you mentioned "out of sync". was that on the same MCP7a machine ? Because if it is then aros booted correctly. In that case the driver uses the wrong frequencies for your attached monitor (usually this is due to edid). You can verify that case by booting your pendrive inside a vm (or attach it to a vm that has aros installed and running) and manually edit the startup-sequence of the pendrive to output some text and pipe that to a file. Then boot the pendrive again on your machine until you receive the "out of sync from your monitor", wait a few seconds longer to make sure the message is written, then shutdown your machine and re-insert the pendrive in your aros virtual machine to verify whether the text you piped to the file is present on the pendrive.
If the text is present then you know aros booted correctly, and in which case the issue is either your monitor (reporting wrong values to AROS) or the AROS driver that does something wrong.
fwiw: the latter case is similar to a situation that i have with a particular machine that i tested in that it does not seem to boot properly when i use the default grub line because it tries to use my (supported) video-card but my monitor is displaying a similar message (for me it is "no input signal received") so i now have to figure out whether:
- aros crashed during boot
- aros booted and runs ok, but selected the wrong output connector (i have both dvi and hdmi)
- aros booted and runs ok, but it somehow gets confused about my connected monitor.
The fact that you seem to be trying this on multiple machines and report on that all at the same time works confusing. Just stick to the MCP7a machine, as that should work (and is reported to work). What the pendrive does or doesn't do during boot on those other machines is really irrelevant. That and the fact that i can't see from here what you have or haven't done in your bios. That you 'disconnected' your sata devices isn't nearly enough from what i can find/see online about the bios in that particular machine, as there seem to be many more related settings (such as the floppy drive settings i mentioned).
