# Legacy workaround
Use this workaround ONLY for systems which cannot boot using standard configuration, as of Feb 2016 this concerns following types of network cards: Mellanox Connect X-2, Chelsio T520-LL-CR, QLogic cLOM8215
## Enable PXE workaround
Make sure your aims2 client version is at least 2.11.
Add affected system to AIMS2:
```bash
# aims2 addhost HOSTNAME
```
Enable PXE workaround:
```bash
# aims2 pxelgcyon HOSTNAME
```
Optional: Set PXE boot target:
```bash
# aims2 pxeon HOSTNAME TARGET
```
Wait until AIMS2 reloads dnsmasq configuration, this takes up to 30s.
```bash
# aims2 showhost HOSTNAME -all
Hostname: HOSTNAME
Interface HWADDR: XX-XX-XX-XX-XX-XX
PXE status: OFF
PXE boot options: none
PXE boot type: BIOS
PXE boot target: none
PXE noexpiry: N
PXE boot legacy: Y

## Enable PXE workaround - alternative syntax
```bash
# aims2 addhost --bios --lgcy --hostname HOSTNAME --name TARGET --kickstart=KSFILE [ --kopts=KSOPTS ]
```
## Enable PXE workaround - ai-installhost
For systems installed using ai-installhost please add `--mode bioslgcy` flag to the command (this is temporary until `ai-installhost` will be able to autodetect affected hardware):
```bash
# ai-installhost --mode bioslgcy HOSTNAME.cern.ch ...
```
## Disable PXE workaround
The PXE workaround stays active until one of the following commands is issued:
```bash
# aims2 pxelgcyoff HOSTNAME
# aims2 pxeon HOSTNAME TARGET uefi
# aims2 delhost HOSTNAME
# aims2 addhost HOSTNAME
```
Installing the system or using `# aims2 pxeoff HOSTNAME` does **NOT** disable the workaround.
