* 86Box A hypervisor and IBM PC system emulator that specializes in

|
* running old operating systems and software designed for IBM
|
|
* PC systems and compatibles from 1981 through fairly recent
|
|
* system designs based on the PCI bus.

* ICD2061 clock generator emulation header.
|
|
* Also emulates the ICS9161 which is the same as the ICD2016,
|
|
* but without the need for tuning (which is irrelevant in
|
|
* emulation anyway).

|

* Used by ET4000w32/p (Diamond Stealth 32) and the S3
|
|
* Vision964 family.
