Most BIOS's have a "Reset System Configuration Data" or "Reset
Extended Configuration Data" option in the CMOS setup. It's always
"DISABLED" by default. It's primary purpose is to recover from memory
or port allocation errors that leave the machine unbootable. It will
also fix overlapping memory map assignments. Set it to "Enabled",
save the settings, and power down the machine. That means pull the
plug and let it sit for a while so that the "wake on lan" feature
turns off the etherknot card. When it boots, the bios will announce
that the ESCD has been reset. With any luck, it should then work. No
changes needed to OSR5.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.
I am a Kerio reseller. Articles here related to Kerio products reflect my honest opinion, but I do have an obvious interest in selling those products also.
Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
