Thanks for the reply, Joey.  I got it working!  I simply had to configure the array using the Perc BIOS (as I had done already), and then turn OFF Legacy Option ROM support in the BIOS.  As soon as that was off, Windows Server installer saw the virtual disk, no driver required!
I'm struggling with installing a Perc H330 in a low-end server (T30).  There's no Lifecycle Controller, no bootable System Management Tools disc (that I'm aware of), etc.  I realize this may not be a supported configuration.  If it simply won't work, I'll move on, but I'm going to keep trying for now. Perc BIOS sees drives (2x2TB), allows creation of virtual disk, RAID 0 array (4TB).  If I boot Windows Server (2019) installer via UEFI, it will not see the virtual disk, even if I load the driver.  If I boot in legacy mode, it can see the virtual disk and install successfully.  But, I'm limited to MBR, 2TB partition size, etc. Any ideas what combination of settings I need to make this work?  I've tried toggling the Enable Controller BIOS setting on and off, but that doesn't seem to have any effect.
