<para>Symbios 53C825[a] will also work as boot adapter. Diamond
FirePort, although based on Symbios chips, is not bootable by the
PC164SX SRM. PC164SX is reported to boot fine with Symbios825,
Symbios875 and Symbios876 based cards. In addition, Adaptec
Symbios875, Symbios895 and Symbios876 based cards. In addition, Adaptec
2940U and 2940UW are reported to work for booting (verified on
SRM V5.7-1). Adaptec 2930U2 and 2940U2[W] do not work.</para>

<para>In summary: this family of machines is <quote>blessed</quote> with a
challenging compatibility as far as SCSI adapters go.</para>
<para>On 164SX you can have a maximum of 1 Gbyte of RAM. 4 regular
256MB PC133 ECC DIMMs are reported to work just fine. Whether 512MB
DIMMs will also work is currently unknown.</para>
<para>PCI bridge chips are sometimes not appreciated by the 164SX,
they cause SRM errors and kernel panics in those cases. This seems
to depend on the fact if the card is recognised, and therefore
correctly initialised, by the SRM console. The 164SX' onboard
IDE interface is quite slow, a Promise card gives a 3-4 times
speed improvement.</para>
<para>On PC164 the SRM sometimes seems to loose its variable settings.
<quote>For PC164, current superstition says that, to avoid losing settings,
you want to first downgrade to SRM 4.x and then upgrade to 5.x.</quote>
