Hey all,

I recently acquired an ELSA XHR Winner 1000 convertible and it's really a wonderful card; more than I could've hoped for, certainly.

I was messing with some dip switch settings after upgrading the card to 2MB of VRAM and noticed that one is titled SS4/SS5. Does anyone know what this refers to? Total Hardware 99 is unhelpful, indicating that this has to do with "Board Configuration," for whatever that's worth?

I have a distant sibling of this card as well--the Winner 1000ISA with an S3 805i--and that card has a dip switch to disable the BIOS and run the card as a secondary accelerator. Is this something similar? I tried the setting and couldn't find any appreciable changes.

Also, as an aside, are these cards that intolerant of 10MHz ISA or is my motherboard just not cutting the mustard there? The card works perfectly at 8.33MHz on the ISA and EISA side, but when running in the ISA configuration, it seems to produce artifacts and distortions at 10MHz ISA on my DataExpert 4409 motherboard. This board is a bit weird; it lacks a proper ISA divider and auto-divides the frequency. At 40MHz, with a DX2-80, the ISA bus runs at 10MHz, as confirmed by an oscilloscope.

Side note: I did in fact find an appreciable difference between the two configurations when the card was used in an ASUS PCI/E-P54NP4. Granted, that's a dual Pentium board and nothing would really be bottlenecking the card at that point, but I figured that was interesting, as it's not what I see often reported in various 486-based configurations.
