If you get a lockup in BIOS press the power button for 4 seconds like it says in the product guide. Remove the CMOS battery 30 minutes, then run the recovery bios. Check to see which BIOS version is listed if you can get your system operational. The general procedure is go into BIOS Setup Utility by pressing <F2> during the boot process. Once in the BIOS setup utility, press <F9> to restore BIOS default settings. Reset any customized BIOS settings. Clear all DMI event logs, which are located in the Advanced/Event Log Configuration section of the BIOS Setup utility. Press <F10> to save the new settings and reboot the system. It isn't clear when you used the Recovery BIOS or which version.
OK, I'm here again!
Since I didn't have video, It was difficult to know what to do without prompts,
Anyway, I found some info here: http://www.technibble.com/how-to-recover-from-a-bad-bios-update/
This guy said I can recover without video prompts using the bios recovery of the manufacturer, but it didn't work. o I downloaded the .ISO update for the firmware and yeah I had video again, the flashing started, but failed again (Using the crappy 2006 bios).
Anyway, I downloaded the 1997 and the flashing failed, so.. WTF?? I cleaned the cmos again, put the jumper in normal mode (no recovery) and it worked (Remember, using the .ISO of the 1997, because the bios recovery .BIO file didn't work,)
I'm writting from my resurrected DX38BT.
Hope this helps for somebody else and I'm here to help with this issue.
