If you know anybody that has a similar DM500C cable box, then they might be able to help you with a bootloader image copy. The telnet command to create this file is:

cat /dev/mtd/2 > /tmp/bios.img

Then FTP the file to PC / usb stck or email it to you. I believe it's a Jtag job to install it to your box, though. Good luck!

Cheers- AL

hi, i managed to extract out the bios.img but it is 256KB .
i thought blimg should be 128KB instead.

No, bios on the old dBox2 was 128kb. For DM500 it is 262,144 bytes (256kb), at the top of the nvram memory map from 0x7C0000 to 0x7FFFFF

Hi, I managed to Jtag 256KB bios.img (renamed to blimg) successfully but I still unable to Dreamup (tried many version from v1.3.2.0 to v1.3.3.4)
Dreamup cannot detect the box.

Are you using a proper serial null-modem cable connected to a genuine 9 pin IRQ Seial COM port on your pc? Because USB to Serial adaptors (if you are using one) are notoriously 'hit and miss' in terms of establishing a serial connection for Dreamup...

Glad you sorted the jtag biz!

yes am using null modem cable (tested DreamUp on another box).
I supposed the Intel flash chip failed.

[jiangou2007]

flashed with few different bootloaders (phillips,alps,cable...) successfully but DreamUp unable to detect when connected by Null modem cable.
Any software program to read the box ip address?
