"Ventoy version 1.0.21 released; still unable to launch my iso files on my machine in “legacy” BIOS, we still end up at the command prompt (initramfs).
On the other hand, the script udev_disk_hook.sh is present in this version and I was able to produce the file / ventoy / log"

Hi, when you drop into the shell, please run the cmd and send me the result:

I don't knwon why it use /ventoy_os_param as the file name. Obviously you input /ventoy/ventoy_os_param
Code:
int rc;
int ch;
int print_path = 0;
char filename[256] = {0};
char diskname[256] = {0};
char device[64] = {0};
ventoy_os_param *param = NULL;
while ((ch = getopt(argc, argv, "c:f:p:v::")) != -1)
{
if (ch == 'f')
{
strncpy(filename, optarg, sizeof(filename) - 1);
}
else if (ch == 'v')
{
verbose = 1;
}
else if (ch == 'c')
{
strncpy(device, optarg, sizeof(device) - 1);
}
else if (ch == 'p')
{
print_path = 1;
strncpy(filename, optarg, sizeof(filename) - 1);
}
else
{
fprintf(stderr, "Usage: %s -f datafile [ -v ] \n", argv[0]);
return 1;
}
}
if (filename[0] == 0)
{
fprintf(stderr, "Usage: %s -f datafile [ -v ] \n", argv[0]);
return 1;
}
param = malloc(sizeof(ventoy_os_param));
if (NULL == param)
{
fprintf(stderr, "failed to alloc memory with size %d error %d\n",
(int)sizeof(ventoy_os_param), errno);
return 1;
}
memset(param, 0, sizeof(ventoy_os_param));
debug("get os pararm from file %s\n", filename);
rc = vtoy_os_param_from_file(filename, param);
if (rc)
{
debug("ventoy os param not found %d\n", rc);
goto end;

Hello
After having copied the file / ventoy / ventoy_os_param on another usb key to access it from a system installed on my machine, it was impossible for me to read the content.
I have this in the properties of the file:
type: modèle (binaire) STL 3D (model/x.stl-binary)
taille: 2.3 ko (2,324 octets)
no applications on my machine that can read this type of file.
Addition: Would it be an STL file (3D printing)?
Here is what it gives by forcing the opening with Gedit:

Hi people,
Any updates on this topic? i experience the same here on an nforce 2 chipset motherboard for intel CPU. On another system even with nforce 2 chipset but for AMD cpu it does not happen - interestingly...
greetings
