BIOS access with F2

Default VMEbus settings need to be changed.
Otherwise, vmebus.ko fails to load as it cannot map enough contiguous memory.

vme_bridge 0000:08:04.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22
vme_bridge 0000:08:04.0: PCI-VME bridge: V1.4 (May, 19 2010)
VME Bridge: found TSI148 VME bridge rev 0x0001
VME Bridge: Using IRQ 22
VME Bridge: Not enough PCI memory space available: 10fffff
vme_bridge 0000:08:04.0: PCI INT A disabled
vme_bridge: probe of 0000:08:04.0 failed with error -12 

To allow for larger VME mappings set default values reserved bounds must be enlarged

• → Vme
  • Outbound Reserved Size [64 MB]
  • Inbound Reserved Size [64 MB]

Both default values are set to 16 Mb. The maximum value is 256 Mb.
Consider the 64 Mb a first shot.
