Hey, thanks.

This actually reminds me that i never updated the charts and original post with Appian ADI2 + driver.
Did it now (you will probably need to hard-reload for local cache invalidation).

It turns out that ADI2 is a great EIDE chip.
As noted in the original post - it works well with CF cards, but a bit flaky with mechanical HDDs.
The reason for that - I am testing on a highly (most) optimized VLB system and that seems to be a bit too much for it.
If i relax system timings - all is good, but at the cost of lowered performance.

I have got the DTC EDPT 32GB extension bios already running on this config:

Pentium 90Mhz classic
FiC PA-2002 motherboard
16MB EDO 60NS (got two sticks (one seems to be dead) (going to upgrade it to 48MB
15GB WD caviar 153aa
VGA Mentor Tseng Labs ET4000 / W32P 2MB PCI
UNKOWN RTL8019 Ethernet NIC 10Mbit ISA with DTC EDTP 2.2a bios ( running 16K part) Limit 32GB.
Going running windows 95 on it.. Perhaps with split Dos mode..(so windows 95 doesnt boot straight to GUI) but ending in dos prompt)

Very intersting Robin4.
I was recently thinking of trying that in a pci network board as well.
