Installed new mpotherboard and on first boot all drives light up and stay lit?

I just installed a new Tiger AT motherboard in an older case.  Seems like I hooked up everything correctly.  When I go to boot-up the Floppy, CD-ROM, and Hard Drive lights all come on solid and stay that way.  No Video signal at all.  Does anybody have any idea what this could be?

The motherboard is a Tiger M598 and has included 8MB Video, 56K Modem, and Sound Card all onboard.

Recheck all the cable connections, make sure pin 1 is lined up right. Try disconnecting everything except the video card and floppy - see if the machine will boot from a floppy. Check the seating of the memory and the cpu. Also make sure the clear cmos jumper is not in the clear position - some boards ship that way

Immediate guess when all the lights are solid is that you have ALL the cables on BACKWARDS!  If that's not true, open the case up, disconnect all devices from the motherboard EXCEPT the power supply and reseat the video card.  Try booting - if you get video, great, otherwise, try a new video card.  If you DO get video, add - ONE AT A TIME - each component to the system, Floppy, Hard Disk, CD-ROM, Sound, Network, Modem, etc.  When/if it stops working, check your connections and make sure the cables are attached right (where applicable), and move on to the next one.

You have got a lot of good advice here, but you might start with a check of the power for the motherboard - The black cabels on the two connectors have to be in the middle...

Did you install your memory in bank 0?
Have you removed your HD and floppy cables to know if the system boots up?
Please, make sure the clear cmos jumper is in the normal position.

also you have to check jumpers for CPU type & BUS speed on MB

Perfect,  you were correct on two counts.  I had the floppy cable backwards, and the cmos jumper was also set to clear.  Thatnk you so much for your help and quick response!
