The down side is that some old GS games and demos won't run. However many of
the more worthwhile ones have been patched.

021- How can my ROM 3 GS + 8MB Sirius card do large file
copying?
An error in the Sirius manual (a 1 page paper) recommends that ROM 3 users
remove one of the SIMM modules since the ROM 3 has 1MB and 8MB is max. When I
did this, the GS reported 8MB, but copying large groups of files or large files
(>800k) failed. When I put the missing SIMM back, the GS still reported 8MB,
but the file copy problems vanished. It appears that the Sirius needs eight 1MB
SIMM modules for 8MB even on a ROM 3.

Turns out I had the opposite experience. In my system (ROM 3 with 8MB
Sirius v2.0 and Focus drive) the large file corruption problems, "ghosties"
(weird video artifacts), random system crashes (especially when Balloon 2.0 was
active), etc. _all_ went away when I _removed_ "SIMM 8". (There is some
numbering on the back of the Sirius.)

022- I just received my Sirius RAM card and populated it
with 8 1MB SIMMS. However my ROM 3 GS crashes early in
the boot process. Could it be a problem with my RamFAST
and DMA?
First, if your RamFAST is the Rev. C (full-length) card, it cannot DMA to
8MB; so, you will have to turn DMA off. The Rev. D can DMA to 8MB fine.
Second, make sure there are 8 SIMMs on the Sirius. Alltech used to say that
you are supposed to take out one of the SIMMs when using the 8MB Sirius card on
a ROM 3; but, this leads to problems. Plug in all 8 SIMMs and use it that way.
You lose the 1MB from the motherboard this way, but you gain it back on the
'extra' SIMM you put in.
