Got this system from a 'friend' to work on.. it is a mid-tower with a micro ATX P4 mobo.. socket 478.
Specifically, an Elite Group P4VXMD (per a sticker on the printer port).
The BIOS string is 12/28/2001-P4X266-8233-6A6LWE19C-00. (Award vers. 1.1E)
When booting, before the OS will start, there is a message 'unknown flash type' on the screen.. and a few seconds halt.
Downloaded the specific BIOS flash (latest..'03) for it, but the flash routine fails.. every time! "Unknown flash type" is the message.
The 'friend' said he bought it from a clearance sale.. it works well otherwise, but can't get beyond 100 Mhz FSB. Runs the installed 2.1 Ghz/533 FSB P4 CPU @100x21!!
OS is Win 98SE. Normal other features.. 256 RAM, 64 Mb video AGP 4x. On-board sound. 40 Gb hdd. 300 w. PSU. DVD reader. Had no manual or driver disks. Had to DL them.
Even with all drives (but fdd) disconnected, and no device cards, the flash will not take.

Methinks there was a bad flash routine, and this is the result.. the manual has no mention about 'flash upgrading protection' jumpers. No locks in the BIOS pages either. Guess it was a 'bargain' to him at 100 bucks. My headache!

That was my first guess too. If it is and you can't reflash I'm not sure what the way out is, except a new chip

I ripped the beast apart, and lo and behold! Some witty-ditty put a connector for the front panel on the jumpers that control the flash protection!!! The mobo manual my 'freind' DL'd was the wrong version model.. looked very similar. The manual I DL'd was the correct one.. and shows the jumper location. Anyway, long story short.. the flash took, and success.. but the original design of the mobo chipsets is a max of 400 Mhz for a CPU chip. Ran Everest as a peek on the setup, noted differences in the CPU intent! Took out the CPU, and found the stepping code is for a 2.8/512/533 design.. the multiplier being set by the CPU keying pins limits the setup to a max of 400 FSB.. no higher! No change in the BIOS to accept a 533 FSB. The setup works very well as-is, and has no hang-ups now.. and no 'unknown flash type' error. Works decently at 2.1 Ghz. Can OC it up to 110 Mhz FSB, but is unstable. Anyhoo, the 'friend' is happier now.. can access large hdd and has stability. It was suggested to get an upgrade of Windows 2000 or XP due to Win 98 being orphaned. And the present OS needs updates for security issues!
At least I get a nice lunch out of this.
