   working at all.  Even with a fresh install of Windows 95.   I'll get an IP but   
   can't ping the gateway, the reply times out.  I didn't change any of the   
   default settings of the driver.   
   .. I think the buffer or whatever was set to RX + TX.   This weekend has been   
   bit busier than I expected and I have to run so.. not sure how much I can play   
   with it more this weekend.  Also... with the fresh install, the 32bit driver   
   for my BusLogic card    
   is intermittently loading... which what the hell?!?!  So I want to nuke the   
   install again and find a more trusted ISO of Windows 95 C.   Downloaded some   
   fresh copies last night and had one fail that it couldn't find a file in a cab   
   in the middle of the    
   install... turns out people commented on the download page that the ISO was   
   wonky.  I dont burn the ISO's to CD-R as ZuluSCSI will emulate them as a CDROM   
   if you put the ISO on the SDCard and name it properly.

   think the reply board is slow in general.  The 486 Overdrive 100mhz and   
   Kingston TurboChip also both score about the same as the POD83... which is 20%   
   slower than any rando board    
   out there that can take these chips.  I've had a few others with the Reply   
   board get the same results.  Not sure why.
