Updating bios with flash drive najrandating
With a little luck, your BIOS System information will look like this screenshot, and reflect your successful addition of a new version to your PC.The best place to get a BIOS update is from your PC manufacturer's Web site, on the downloads page for your notebook or desktop PC, if you purchased a complete system, or for your motherboard if you built your own system (or purchased a "white box" PC from somebody else who builds them from stock parts).You'll also need a USB Flash Drive (UFD) formatting tool that can create a bootable DOS image on that drive.This requires a special formatting tool, and DOS source files to make the drive bootable.BIOS determines whether the motherboard is set for normal operation or a continuous loop of POST.If the POST test is cycled 1-5 times over and over either the jumper for this function is set to burn=in or the circuitry involved has failed BIOS checks for any extended information of the chipset and stores it in the extended RAM area.See the Press Tab...message earlier for a description of this feature Initialize 6845 video controller, 8237 DMA controller, 8259 PIC, 8253 timer channel channel 1 initialized; Reset math coprocessor; Disable color and mono video, parity circuits and DMA chips; Clear DMA chips and page registers Keyboard initialization; Initialize NMI, PIE, AIE, UEI, SQWV; Disable video, parity checking and DMA; Math coprocessor reset; Clear all page registers and CMOS RAM shutdown byte; Initialize timers 0, 1, 2 and set EISA timer to a known state; Initialize DMA controllers 0 and 1; Initialize interrupt controllers 0 and 1; Initialize EISA extended registers Initialize chips; Disable NMI, PIE, AIE, UEI, SQWV.

Don't flash unless you really must, and never flash without making a backup and rounding up necessary repair tools.
If you assumed the system would boot from the hard drive, make sure the controller is inserted correctly and all cables are properly attached. Check validity of RTC value; Load CMOS settings into BIOS stack.
Also be sure the disk is formatted as a boot device. If CMOS checksum fails, use default value instead; Prepare BIOS resource map for PCI & Pn P use.
Also, be sure the card in installed firmly in the slot Cannot initialize controller.
Make sure the card is correctly and firmly installed in the bus.
