Solution:

Because the network configuration default setting of rev. A1 and A2 is different, You need to check it first. Rev. A2 300H IRQ3. Rev. A1 240H IRQ3. Please use diag9008.exe to change your configuration. ######### Example case ########################## I've test it for you and confirmed this problem. Actually, Chen Hua told me that Haixin is using POS-460 A2, so i think it uses UM9008AF as its LAN chip. However, I can't find any problem on this version. Meanwhile, I have also test myself by creating ethernet boot diskette from WinNT Server, but still ok. So there is no different on both your attached ethernet bootup installation program, and I think it must be something wrong on our information. After change to A1 version which with UM9007AF, I got your problem. But finally I see your words on the email, that is just because the firmware (eeprom) setting is different with the PROTOCOL.INI of the NET directory. So after modify the configration, this problem can be solved. You can find the following session to see the confirguration: (Note that I/O 0x300 and IRQ 3 is for the default values after MS Nework Client 3.0 installed. And the UM9007AF default values usually be I/O 240, IRQ 3) [MS$NE2CLONE] IOBASE=0X300 INTERRUPT=3 DriverName=MS2000$ If you don't have the SETUP.EXE which is the utility to modify configration of UMC9007AF. please find attached files for using (It is DIAG9008.EXE for UM9008AF). Also, I attached with UMC9008AF utility at same time. Meanwhile, please be sure of that WinNT Server has create the new user for POS-460 login.
