BTW, looking at the Promise code I see

quoted

cam_con.h:
/* for ASIC bug, limit the last element of SG byteCount must < 32
Dword */
#define SG_COUNT_ASIC_BUG       32
//#define SG_COUNT_ASIC_BUG     128

    and in the code itself

quoted

/* check PRD table, last element <= (32 Dword), fix ASIC bug */

(though the code obviously uses SG_COUNT_ASIC_BUG==32, as the first
paste indicates)

so it seems like Promise first used 128 (32 dwords), but then backed
down to 32 (8 dwords).

Which version is this define from?

Both versions that are available now from their website define it at 41*4:

You're looking at the old pdc-ultra2 driver. The newer unified
sataii150-300 driver (v1.01.0.23) upped the value to 41*4.

I was looking at pdc-ulsata2_1.00.0.15.tgz, which was the latest driver 
that Promise's website gave me to when I listed "SATA300 TX4" as my product.

Sounds like that is outdated information, thanks for the correction!
