SiS83C601 hard disk controller not found

Hi all

I am trying to install freebsd on an old laptop but sysinstall can't see the hard disk. The machine is a Pico 6200AT - I'm pretty sure it's a rebadged Clevo 6200AT.  It doesn't boot from CD so I'm booting from floppies 
using kern.flp and mfsroot.flp. When I try to set up a partition I get "No disks found! Please verify that your disk controller is being properly probed at boot time. ..."

The IDE controller is SiS83C601. Output from Sandra system analyser software is

<< Silicon Integrated Systems (SiS) SiS83C601 PCI Enhanced IDE Controller >>
  < Device Information >
    Device Type:                   ATA Disk Controller

    Revision:                      A / 2 (1)

 Sandra also notes:

  < Performance Tips >
    Tip 1202:                      Device does not support bus mastering.

I found a very similar issue in which says it has been fixed since 4.2.

I tried with 4.10 and 4.9, also 5.2.1 which gave a different message but looked like the same failure (I can give the details if relevant)

I also tried 4.4 and got

ata0-master: ata_command: timeout waiting for intr
ata0_master: identify failed
ata1-master: ata_command: timeout waiting for intr
ata1_master: identify failed

Can I install or should I give up? I wondered if it is that the relevant driver is just not on the boot floppies.

Thanks for any help
