NETBIOS.OS2
This is the NetBIOS API driver.
DEVICE=\IBMCOM\PROTOCOL\NETBIOS.OS2
TIP: By Roland Sambain. The conventions wisdom about IFS statements coming at the beginning of config.sys seems not to apply. i.e. for NetBIOS to load correctly the device statement must comes before the NETWKSTA.200 IFS.
Netbios and Gigsabit adapters
Due to the nature of NetBIOS, it has some limitations to work on Gigabit adapters with requires some adjustments to MPTS settings.
Explanation: NetBIOS can not work with large Ethernet frame sizes which are used by default with Gigabit Ethernet adapters. Both transfer and receive buffer sizes should be set to 1024 bytes and USEMAXDATAGRAM set to "NO". The DIX 2.0 protocol type (ETHERAND_TYPE) should be set to "D".
Procedure to change settings
- From MPTS select 'Configure'
- In 'Current Configuration' find the "IBM 1000BaseT Gigabit Ethernet Adapter" and press 'Edit'
- Set 'Receive Buffer Size' = 1024
- Set 'Transmit Buffer Size' = 1024
- Select OK
- In 'Current Configuration' find the "IBM OS/2 NETBIOS" and press 'Edit'
- Set 'Type of Ethernet driver support = "D"
- Set 'Full buffer datagrams' = "NO"
- Select OK
- Select 'Exit' MPTS.
- Reboot
The other possibility is to use "IBM OS/2 NETBIOS OVER TCP/IP". You might want to try this and compare the results to native NetBIOS.
