md5sum: f8243cfa1fe384b245cd50aad596ba5c netboot.xyz.usb
It gives me this when I copy it to a USB key on linux:
[8485557.262586] sd 11:0:0:0: [sde] Write cache: disabled, read cache: enabled, doesn't support DPO or FUA
[8485557.270013] sde: sde3 sde4

Command (m for help): p

Units: sectors of 1 * 512 = 512 bytes

Disk identifier: 0x00000000

Device Boot Start End Sectors Size Id Type
/dev/sde3 32 2047 2016 1008K e0 unknown
/dev/sde4 * 2048 6143 4096 2M eb BeOS fs

Neither partition is mountable, the BeOS one is not even mountable as befs

Note that even freshly downloaded, the file has the wrong partitions it seems (so it's not an issue with my USB key):
file netboot.xyz.usb
netboot.xyz.usb: DOS/MBR boot sector;
partition 3 : ID=0xe0, start-CHS (0x0,1,1), end-CHS (0x0,63,32), startsector 32, 2016 sectors;
partition 4 : ID=0xeb, active, start-CHS (0x1,0,1), end-CHS (0x2,63,32), startsector 2048, 4096 sectors

Your image is too big. Perhaps you've did something to it. Here is the latest dump.

Image is no more published in "usb" form

https://boot.netboot.xyz/ipxe/netboot.xyz.usb

it was convenient to use also new partitions
