[comp.sys.sun] MS-DOS on SparcStation 1 ?

NE08@DKAUNI2.BITNET (02/08/90)

I've heard that there is an MS-DOS emulation mode on the SS1 so that you
can run MS-DOS applications on this machine.  The speed of the emulation
is said to be approximately that of an 8MHz AT.

Does anybody have information on this ?  Does anybody know how good the
emulation is, i.e. which programs will run on the SS1 and which will not ?
Any comments welcome.

Please E-mail to me, i'll summarize if there is enough interest.

You can buy it from Sun and it is licensed to the hostid of the machine.
It is not compatible to the emulation on the RoadRunner (Sun 386i) - so
the emulated harddisk on the two machines are different etc.

Also the emulation (?!) on the 386i is more compatible than on SS1, I
tried some games which hang on the SS1 but run on the RR.

The MS-DOS emulation on the SS1 has a bug that affects a lot of software.
I have not been able to get a reply from SUN either through my sysop or
directly.  A colleague in Japan has isolated the bug:  DosWindows does
not--or maybe just does not always--emulate the 80x86 RCR command
correctly.  Specifically, the 8088 source line

RCR WORD PTR [SI],1
is emulated as
SHR WORD PTR [SI],1.

If anyone has information on a fix or update, reply to me directly, and I
will summarise useful information.
