Loading firmware on the Blackberry 7230

by on Aug.22, 2009, under General Jazz

If you are trying to load firmware on a Blackberry 7230 or 7290 with a recent version of the Blackberry Desktop Manager, it will consistently fail. I encountered such a problem this morning. Tried using JL_Cmder, but still no luck. It would would quit with the error “COM error during open”.  It had no problems connecting to the 8700 and 8310 Blackberrys.

I decided to downgrade the Blackberry Desktop Manager to v3.6 which I had laying around on a memory stick. Installed the v3.6 after a quick uninstall of  v4.7. Tried the firmware load on the 7230  and it went through without a hitch. JL_Cmder also works fine now with both the 7230 and 7290.

Issue discussed in  GSMForums.

Infratec PM 8-IP

by on Aug.08, 2009, under General Jazz

Quick glance
A power strip with 8 power outlet sockets and 2 power inlets. Each power port can be turned on or off individually over the network. Support for this product on Infratec’s website appears poor at best with documentation being equally sketchy. e.g., the firmware revision on my PM 8-IP is 2.02, whereas the latest available download on the website is v1.26a.
Details
One would be misled into believing that the dual power inlets ensures power redundancy. Unfortunately not, each power inlet can power its own set of 4 power outlets. Hence not entirely useful for critical datacentre operations.
On the networking front, it runs Ubicom’s IP2022 network processor. The network is up and running in about 2 seconds after power up. Pretty impressive. Power to the network processor/controller is supplied only from one of the power sources.
The console serial port (RJ-9 4P4C socket) running at 9600-N-8-1 can be used to configure the IP address and also for performing a factory reset (highly recommended after a firmware up/downgrade.) The unit can be factory reset by pressing “F” (case sensitive) when at the console menu. In some cases the web server becomes in accessible after a firmware upgrade, and a factory reset is required to bring things back in order.

I constructed a console cable from an old RJ-9 jack and a DE9-F connector. Use the table below to wire up the two connectors:

PM 8-IP (RJ-9 4P4C) PC Serial port (DE-9)
1 (GND) 5 (GND)
2 (TxD) 2 (RxD)
4 (RxD) 3 (TxD)

Installing WinXP with Intel AHCI drivers

by on Jul.18, 2009, under General Jazz

I was trying to load XPSP2 on an Acer Aspire 4810T. I downloaded the XP AHCI drivers from the Acer site and tried to load the AHCI drivers from the floppy. It refused to give me the AHCI options, only RAID drivers!

Looked around a bit on the floppy and figured that the drivers are there but it doesn’t show up during the install. Haven’t fully figured this out, but the TXTSETUP.OEM needs to be modifed. I modified it and got the AHCI drivers to load successfully from the floppy.

Here’s what you need to do.
1. Open TXTSETUP.OEM in Notepad or any other text editor.
2. Locate the line that says :
scsi = iaStor_ICH8MEICH9ME

3. Change it to read :
scsi = iaAHCI_ICH9MEM

Start the XP install again with F6 and now you will get the option to load the AHCI drivers.

Hoping this helps someone out there.

IBM Thinkpad T30 BIOS password

by on Jul.15, 2008, under General Jazz

I came by a IBM Thinkpad T30 with a power on password enabled. The original owner threw it out because he couldn’t remember the password and IBM told him that he had to change the planar (the notebook equivalent of the motherboard.) Followed the instructions on SoDoItYourself and constructed a serial port interface, downloaded the software and I was very quickly able to get the power-on password!

Neat!

Philips monitors “Aging…”

by on Jun.01, 2007, under General Jazz

Philips 15″ monitors enters the “Aging…” mode when the power button is held down for more than 3 seconds. Switching off the monitor (even for days) does not reset the monitor.
The mode is exit only when the monitor is connected to a PC.

My $0.02 on the subject
