Woo hoo!
Just installed os4.1 on my A4000 in a mediator tower tonight. typing this on OWB and just had to tell....someone!
Surprisingly after i set up the cf's with sfs and formatted them,it was just a matter of booting the install floppy/cdrom which worked on the radeon as is,i didnt have to do anything other than set the res in sys:prefs/screenmode to what i wanted. no mediator driver sillyness to install like under 3.9.
other than that i started the tcp/ip install and picked the rtl8029 driver and quieried the card and it found it,entered my ips/gateway etc manually and i was online.
Most of this stuff works fine and other than the mediator drivers etc its prettyclose to the old os4x install.
I have not mapped any radeon ram to the os,not sure if i will. i will say this,the zoram with 256MB is probabaly a necessity if you do much in OWB.
My Machine Configuration:
A4000 desktop board in the mediator pro tower
Cyberstorm ppc 604e/233 060/60 128MB ram
Zoram board with 256MB that just came in from amigakit(why are these so damn expensive!?)
Sapphire radeon 9250 i got new off ebay for $15..128MB ver.(it works in +5 or 3.3v mediators) my mediator is 5v.
2-32gb kingston pro cf cards adopted to the cyberstorm UWscsi with acard AEC-7720UW scsi/ide adapters.the cf's are the ones i've been running for 5+ yrs.
Deneb usb(havent installed drivers yet!)
rtl8029aas ethernet card(i hate i cant use my 100Mbit card with fastethernet.device!)
SB128
HD floppy
Dvd burner also adopted to the scsichain with the 7720uw.
So far everything is running well,i am using 1600x900 in 32bit res on workbench and its pretty nice.
OWB seems to work well,its not blistering fast but no worse than ibrowse speed wise. its nice to have a useable css browser but i already miss ibrowse download manager.
Has anyone got the sata card to work or was that not for the classics??
I havent' installed it yet but its on the list to try tomorrow.
we need a driver for the fastethernet.device..hint hint

if anyone cares,this was the radeon i got off ebay:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=160603380919&ssPageName=STRK:MEWNX:IT#ht_5978wt_911it worked right out of the box.
I will try and report more on this thread as i get stuff going,i think thats enough for tonight.:rtfm:
