X870 Steel Legend WiFi BIOS 4.xx no boot

X870 Steel Legend WiFi -

I have tested all of the following BIOS: 3.16, 3.26, 3.40 & 3.50. These all boot to Windows 10 but sometimes seem to get lost the first time doing so.

I have tested BIOS: 4.03 and 4.10 and NEITHER of these will boot to Windows no matter what settings that I use.

I am using the Ryzen 5 9600X, Samsung SSD, M.2, G.Skill approved 2x 16 GB DRAM F5-6000J3238F16GX2-FX5, Sapphire RX 480. All of the 3-series BIOS run fine at the default 4800 or Expo 6000 frequences. Neither 4.03 nor 4.10 BIOS will boot to Windows at either default or Expo settings, though they will boot to the BIOS set-up screen.

I have submitted 2x Tech Support Tickets over the past 3 weeks with confirmation that they have been received by Asrock Tech Support yet no response what so ever on the 4-series BIOS refusing to boot to Windows at least with my mobo serial # H9M0XB1098xx.

My past Asrock support has always been good so it's unclear where the issue is.

Thanks for creating a thread for this issue.

With either BIOS 4.03 or 4.10 - yes the system boots only to the BIOS screen - no matter what boot settings that I use - including the boot settings that work fine for all of the 3-series BIOS. I tried every combination of boot settings and neither 4-series BIOS will boot to Windows.

I finally managed to get BIOS V 4.03 and 4.10 to boot to Windows. What I discovered - with YOUR help - is that with the 4-series BIOS it is MANDATORY that you select the boot drive via F11 on the first boot after changing the BIOS. This is NOT the case with any of the 3-series BIOS versions I have tested / been using.

I also noted that CSM in my case MUST be "Enabled" same as in the 3-series BIOS. I am on Windows 10.

In addition I do not see in the boot tab:

"Launch Video"

nor

"Launch Storage"

It appears that Asrock has changed the names or options to something else. It appears they have changed the actual video choices as I do not need to select the "Legacy" option as in the 3-series BIOS. I just used the default settings for the second and third boot tab choices.

You'd think if Asrock was changing these settings they'd at least make people aware as it's a nightmare trying to figure out what has changed or what needs to be changed. There is no reference to bottom two BOOT tab settings in the 63 page User's Manual that I printed out - because a UM is no longer included with the mobo purchase.
