When mounted or extracted, a typical PROBD 910 InstallerISO contains:
/BOOT/ - Custom GRUB or LILO (legacy bootloader)
/INSTALL/ - .bin, .flb, .dbs files
/TOOLS/ - DOS-era .exe, .com utilities
/DRIVERS/ - .sys, .vxd for Windows 9x/NT/2000
/AUTORUN.INF - For Windows autorun (dangerous)
/SETUP.BAT - Batch installer
/README.TXT - Minimal, often in German or Japanese
Key observation: No modern package management, no signature verification, no live filesystem (like squashfs). This is a firmware provisioning tool or proprietary OS installer for a specific embedded device.
Likely workflow:
Even with a perfect ISO, issues arise. Here is how to solve the most frequent problems.
| Error Message | Likely Cause | Solution |
| :--- | :--- | :--- |
| No PROBD device found | The unit isn't powered or the cable is faulty. | Check if the PROBD 910 has an external power LED. Try a different USB port (USB 2.0 is more reliable than 3.0 for flashing). |
| ISO boot fails to black screen | UEFI vs. Legacy boot mismatch. | Enter BIOS. Disable "Secure Boot". Enable "CSM" or "Legacy Boot". Try the "Safe Mode" GRUB option. |
| Flash write error at 0x7A3F | Corrupted sector on the PROBD 910's EEPROM. | Run probd-repair --bad-blocks. Then attempt the flash again. |
| Checksum mismatch after flash | Transient bus error or wrong ISO version. | Re-download the ISO (ensure it's for Rev C, not Rev B). Reboot the host machine and retry. | probd 910 installeriso
Guided install recommended for typical users. Manual steps for UFS2 on GPT:
Format root as UFS2:
newfs -U /dev/da0p2
Mount and prepare:
mount /dev/da0p2 /mnt
mkdir /mnt/boot
If using ZFS (if installer supports):
