The Thing I'm Not Sure About Is Eprom Burning Module,
My Basic Problem Is Boot Failure Message On Startup Pmp-140 Wont Accept Firmware Current Version 1.24 I Have Tried Everything To Recover It But No Luck. If You Can Suggest Anything I Would Be Willing To Listen, Hope I'm Barking Up The Right Tree And Not Just Barking Mad.

Hi Terry! Yes...in your computer, you have the battery that keeps a charge to the CMOS. Exactly. If you were to remove the battery---only the date and time stamps would be lost---but...the FIRMWARE would be retained in the BIOS CHIPS aka: an EPROM chip. BIOS chips only get cleared by having a charge applied to their memory locations and not by having the CMOS battery removed, which does not affect the BIOS firmware/software.
Most older legacy motherboard manuals show where you can flip a switch and or press a button to CLEAR the BIOS entirely and have it ready to accept a new BIOS flash of which the power to do so is made possible by an on-board capacitor. That feature was manufactured in by the manufacturer. Unfortunately----this is usually to be found on 10 year and older systems as you did this under a pure D.O.S. environment and not through Windows. Now, the BIOS is usually only cleared and updated by a download (Flash). Most modern EPROM BIOS chips are socketed, so you can merely put another one in its place instead of having to clear it manually. If the T10 and other iRiver DAPS had a firmware chip that was socketed---you'd only need to remove it..and drop in the new EPROM chip from iRiver. But sadly, that is not provided in hardware---hence my 'get around this' number of posts.
When you do it the way I am talking about (that is..by applying a wire connection between two pins on the chip) you have just created a
virtual button for clearing the EPROM where none was provided in hardware by the manufacturer. You perceived this at 100 percent my friend!
Terry, are you telling me what comes up on your T-whatever DAP, or on your computer?
BTW, the EPROM burning module is a stand alone piece of hardware that you would place the EPROM into (a socket on the module for that purpose) and then download your firmware software onto the EPROM. This is done most often today through a 'soft' module (iriver firmware updater) software interface.
