..........Yippee! You did it!
I cannot thank you all enough for your kindness and dedication in researching and posting the replies above.
Mac's suggestion of rewriting the Autoexec.bat file with the old BIOS did not work when I tried it using two separate disks, but when the Award flash/Autoexec/Old BIOS were added to the bootable floppy files on one disk (Sorry I didn't read the instructions properly first time) the machine showed a little life. I pressed the enter key after the first reading of the floppy, and lo and behold the screen burst into life and offered to load the BIOS.
This it did, and on finishing instead of pressing ctrl/alt/del I pressed escape first and then rebooted. I now have my beast back in fine form, reading the full 768mb of RAM and the graphics card playing fine.
My wife is in tears of happiness, the dog's are barking for joy....as they now think that I might be a tad happier to live with again!!
My thanks to you all once again.
Now does anyone think I ought to have a go at reloading that upgraded BIOS again?.......
