Skip it, not worth it.........
Just forward my mail address to Soren........or I will ask Michael...
WAIT..........GO grab your teflon underware........

This almost verbatium my code design and method........

Now GO explain the full "32-bit" parsing of the timing code!
I have the Specs.........
Also interrupt prediction can cause problems........
Where are the split interrupt, split pin, detections and corrections?
Where are the work arounds for the two know supported modes of the
chipset, and the third mode I discovered and explained it to the enginner
that designed the chip!
Where is your AMD 7409 Viper South Bridge ATA-66 support?
Where is your CMD 643-646-648 support?
Where is your SiS630-620-540-530-5900-5600-5591-5512 support?
Where is your AEC6210UF support?
Where is your Ali 1543C-B, 1543-E, 1543-F, 1543C-C, 1543C-D, 1543C-E, 1535, 1535D,
1553 support?
Where is your HPT343 and HPT345 support?
Where is your IA-64 for (unnamed, I can't tell you that info) support?
Where is your Promise Hardware RAID, (how?? I can't tell you that info) support?
Where is your support for code I have not and can not release yet?
Where is your support for ATA-Hardware-RAID for a 320GB Raid0?
Where is your support for HOT-SWAP ATA-ATAPI (I have not written the
industry standard yet, but will submit a proposal to the T13 standards
committee for discussion on FEB 24, 2000) that does not exist yet?
The list is much much longer........but, I can't tell anyone that info yet!
Now that is done........go take a cold shower and head off to the ER for
the skin transplant in the burn center...
</!!!!!!!!!!FLAME OFF>
You pick a bad night to belly up to the bar......for a CASE of WHOOPASS !!!
Later.............
Everyone please ignore the bait............This is someone that had a wild
hair up the backside.........I really do not care that FreeBSD is using
Linux ATA/IDE all but verbatium........just acknowledge the fact that
Linux paves the way for JAFO's........
