HP EliteDesk 800 G4 DM 65W
Intel i5 8600 3.1 GHZ with Intel UHD 630 graphics and Intel i219LM NIC integrated chip.
AOS v 5.1 with WSeB
Ports
There are six USB 3.1 Type A ports on the front and back, and one USB 3.1 Gen 2 port on the front, plus one Configurable Option slot in the back which can contain a DisplayPort 1.2, HDMI, VGA or USB Type-C with alt mode display, USB Type-C with power delivery, DisplayPort 1.4, Thunderbolt 3.0, Serial Port, or Fiber NIC port.
Memory
It has two slots for DDR4-2666 memory for a maximum total of 32 GB.
MEM.EXE reports 3,110 MB accessible to system
Storage
Storage consists of 2 PCIe v 3 NVMe v slots and one non-standard SATA “slot” which requires a special cable - and its own fan. HP makes a caddy that contains a standard SATA socket and ribbon cable for connecting the SATA drive to the motherboard plus a fan that must be connected to the motherboard connector - see picture. If you connect a drive to the SATA connector and do not connect a fan you will get an error message on bootup that the fan cannot be detected: you can hit Enter at the error message to continue booting. The caddy is designed to fit the location where the NVMe SSD drives reside and there is not enough vertical space to position the caddy with NVMe SSD drives installed. You could however attempt a customized install of a SATA drive without the caddy - it will run with both SATA and NVMe SSD drives attached.
Network>
Intel Pro/1000 Network Driver (MultiMac32-E1000B)
With this adapter and driver the transfer speeds using Netbios approximately 28 MB per second - AOS to AOS. With AOS SAMBA 3.6.25 to WIN10 approximately 39 MB per second. (Times reported by Explorer for Win10 and Larsen Commander for AOS.) I have seen speeds as high as 95MB second when transferring from Win10 to AOS.
Power Usage and Sound
The machine does have an internal fan but in most situations the fan spins very slowly and cannot be heard. Running two NVMe SDD drives the power usage at the desktop without the screen saver running is 14 watts.
Audio
To get sound working with UNIAUD you need to submit a ticket to Arca Noae with a test log in order to get a special driver along with the address needed to supply the driver in CONFIG.SYS to make UNIAUD work.
Video
Panorama or unaccelerated SNAP. Both are more than fast enough.
I had a problem running VLC with Panorama where the system would freeze up at the end of a video. Installing SNAP made the problem go away.
Win-OS/2 and DOS
Win-OS/2 and DOS run but only in full screen mode.
