Re: Problems installing Debian on a 486



There is one more thing.....
On 286's and above when in real mode, if the segment register is set to
0xffff then the address's above 0xffff will overflow into address bit
a20 giving access to an additional 65k(-16 bytes) of memory in real
mode.  This was known as 'hi-mem' access and dos 4.0 and above used this
trick. (meant turning that a20 gate on to allow a20 through).
