Rohde & Schwarz CMU200
msraya:
Thank You _Wim_ but The BIOS does'nt recognize the Hard Disk.. son I cannot make anything..
The screen freezzes in Detecting HDD Drive.... and I must make a hard reset.
It could be the BIOS versión, I don't know..
I have the backup file, no problem, thanks to your post, that I read before..
So, I must found an HDD that Works with that BIOS.. I need perhaps a HDD of no more than 8GBytes. A Compact Flash with adapter would be ideal..
Regards
Manuel
_Wim_:
I also tried a compact flash with adaptor first, but had no luck with that. (I tried with this one: http://www.dx.com/p/sd-to-2-5-ide-adapter-card-227040)
PartialDischarge:
First thing on arrival of the crtu I did make a security copy of the hdd with sucess. It uses a fujitsu 120Gb MHV2120AH, had to buy the same one, but I guess any iDE hdd with higher capacity would have done it. I did a brute force copy ( with the dd commmand) from the hdd to my computer and back, the whole thing took 17 hours to complete!!!

I have backed up both CMU200 & CRTU-RU with the portable tool _Wim_ suggested http://hddguru.com/software/HDD-Raw-Copy-Tool/ :-+
Like _Wim_ I removed drive, attached to USB>IDE adapter (GL811E chipset - very old one I had lying around) to make the image. Takes around an hour or two and your done.
The HDD-Raw-Copy-Tool tool does a sector by sector copy of the entire drive. The resulting RAW image can be opened by a tool like PowerISO and this what I used to upgraded the CMU200 DOS software.
Both the CMU200 Celeron and CRTU-RU Pentium III boards have worked with various Fujitsu 20GB and IBM 30GB IDE drives I have connected. BIOS has autodetected all OK. I have replaced the CMU200 drive with Kingspec PATA IDE 2.5" 32GB SSD and again HDD-Raw-Copy-Tool was used to write the image to the drive before installation. Now the CMU200 boots like a rocket.
I note the Award BIOS FLASH tool and bios image can be found in \internal\install\bios folder. Run the batch file FLASH.BAT to reflash.
Oh, and something I haven't done for years, plugged the IDE cable incorrectly and burnt out a power wire. Thought the CRTU-RU had smoked it was just the wire. The SSD comes with same type of IDE cable - just longer. Put my glasses on this time when I reconnected it and everything ran fine.
Another tidbit - the Windows 2000 default password for user Administrator is blank on the CRTU-RU. Which is good as I haven't found a way to successfully boot from USB flash drive yet.

The free software FreRes from Rohde & Schwarz allows to make sweep and test for example filters or duplexers.

Hi Manuel,
Are you using RS232 or a GPIB adapter with FreRes? Also, how fast is the sweep rate?
Thanks,
David
