Ping times from my NT box to the Sparc are under 10ms. I was having the darndest time with an NE2100 dropping packets and other such nastyness. One day surfing the BIOS setup I got to wandering, "what does CLK2/8 mean when referencing ISA speed?" It means the ISA bus is being clocked real slow. Things worked much better at CLK2/3, which might or might not be 11 MHz on my 486DX33. Had to replace the NE2100 with an NE2000 clone in order to add an Adaptec 1542CF. Ftp rates dropped from 400k or 600k down to the 200k to 250k range. Oh well, SCSI is more important. -- David Kelly N4HHE, n4hhe@amsat.org, dkelly@iquest.com ============================================================= To invent, you need a good imagination and a pile of junk. -- Thomas Edison
