Buggy BIOS?

/boot's timeout is done by calling a BIOS function repeatedly to ask for
10-millisecond delays (checking the keyboard between delays).  The BIOS
function is INT 15h, AH = 86h, with CX:DX == 10000 decimal.  (See
http://www.ctyme.com/intr/rb-1525.htm).

Another possibility: make sure that /stand/etc/default/boot has the
timeout setting in it.  That's the actual file read by /boot.  Normally
/etc/default/boot is copied there during a shutdown, but there are ways
that can fail.

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.

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.
