CDROM/DVD emulation does not work with Windows 11 #109

Closed xardomain closed 1 week ago

xardomain commented 1 week ago

Steps to reproduce: 1) Download 1.20 official firmware from https://github.com/sipeed/NanoKVM/releases 2) Flashed a microSD 32Gb (SanDisk Ultra) 3) Inserted into NanoKVM Full 4) Connected to a desktop: HW: Processor Intel(R) Core(TM) i9-14900K 3.20 GHz Installed RAM 48.0 GB (47.7 GB usable) BaseBoard Product TUF GAMING Z790-PRO WIFI

OS: System type 64-bit operating system, x64-based processor Pen and touch No pen or touch input is available for this display Edition Windows 11 Pro Version 23H2 Installed on ‎1/‎13/‎2024 OS build 22631.4317 Experience Windows Feature Experience Pack 1000.22700.1041.0 5) Network connected to a TP-Link switch, acquired an ip address using DHCP: Image Version2024-08-08-19-44-bef2ca.img Firmware Version1.0.0

6) Downloaded the following ISO from the pc and copied into the virtual disk: Fedora FC40 Network Install https://download.fedoraproject.org/pub/fedora/linux/releases/40/Everything/x86_64/iso/Fedora-Everything-netinst-x86_64-40-1.14.iso SHA256: 4d1c0a7dda6c1d21a1483acb6c7914193158921113f947c5a0519d26bcc548b2 MD5: f7d36e9c364bc56df7b27a63642dd652

7) Verified MD5 on the USB disk, it matches 8) Ejected the USB disk from windows 11 9) Rebooted the NanoKVM using the reboot command from Terminal 10) After reboot, Ejected the USB disk from windows 11 11) Mounted the iso image but I get the error: "You need to format the disk in drive f: before you can use it" 12) Updated the firmware from 1.0.0 to 2.1, same results

It seems that the command issued for the USB gadget is more like mounting a partition in rw than a .iso file to emulate a CDROM/DVD in ro.

@xardomain Hi, by default, USB Gadget will mount the third partition in the TF card. After inserting it into the computer, the computer will recognize an ExFAT disk of about 23GB. When copying the .iso file and selecting the file for mounting on the webpage, Gadget will mount the iOS image separately. Then, when your computer is in boot state, it will recognize the ISO image disk and start installing. But the computer system has started, the mounted ISO image is generally not recognized by the system, so a formatting reminder will pop up

Just now, I burned the image you provided with a real USB flash drive (not NanoKVM) and found that it would also pop up a formatted window in Win11. The virtual USB flash drive function of NanoKVM only simulates a installable USB flash drive, which performs the same as a USB flash drive in many cases. If you want to simulate CDROM/DVD, maybe you need to modify the NanoKVM system:/etc/init.d/S03usbdev, which has the initialization option for USB Gedget

Hi, many thanks. I fiddled with S03usbdev and I was able to get the iso working, in a way I needed (boot from it). I would like if possible: 1) mount an iso as it would mimic a CDROM/DVD from web interface (feature request) 2) mount a partition (as it currently works) but decided if I want it read-only or read-write (feature request) 3) should it be a way to refresh/sense when in the images change/are added. If I understand correctly, you need a kvm reboot to sense a change in the images (feature request).
