Hardware: Soekris Net4801 (ComBIOS 1.21), SanDisk 512MB Ultra Compact Flash Software: 5.1-CURRENT Symptom: ad0: FAILURE - SET_MULTI status=51<READY,DSC,ERROR> error=4<ABORTED> GEOM: create disk ad0 dp=0xc47ffb70 ad0: 488MB <SanDisk SDFCH-512> [993/16/63] at ata0-master PIO4 Result: system boots normally and runs without problems Hardware: Soekris Net4801 (ComBIOS 1.21), SanDisk 512MB Ultra Compact Flash Software: 4.9-RC4 Symptom: Read error (BIOS? initiated) Result: hung Note: Hardware in scenario #1 and scenario #2 are the same pieces of equipment (not just similar). Analysis(feeble): This Compact Flash card does not support multi-sector transfers required to boot. 5.1-CURRENT is compensating for this effect and continues. 4.9-RC4 punts (returning an error to the BIOS?). The recent delay of 4.9-RELEASE may indicate that there is some small window in which to obtain a fix for this problem in a "STABLE" release (before 5.2). I hope.
