I've been having this same error message pop up during boot up for quite a while now(about 1 year).Although it's not,in any way,badly affecting my system performance, I'm just curious to what it might be.I have a feeling that it requires me updating my BIOS. However, I fear doing that in account of all the ghost stories I've heard of people having unsuccssesful attempts in upgrading and having ruined their BIOS chip only to having to get another motherboard.Like I've said before;I'm not too concerned about this. I guess I'm just curious. Specs:AMI Bios (Version Unknown) Adaptec AHA-2940AU SCSI adapter Plextor 32x CD-ROM Plextor 8/20 CD-R Thanx In Advanced =)

switches on many scsi controllers can configure them for amongst other things, whether or not to enable the bios on the card.So you never see the CTRL-A option .Not so the 2940AU. All it

If you aren't booting from a SCSI HDD then the bios 'decides' not to load. You only need the SCSI bios to load if it needs to superimpose itself on the main motherboard bios in order for the pc to boot. If, as I suspect, you are only running a SCSI CD Writer and or CD-Rom then it's not a problem. Many motherboards have onboard support for Symbios SCSI controller chips (used mainly by Tekram) and have an annoyng habit of overriding the SCSI Card bios with the onboard SCSI 'support'. I think this is mainly legacy support as I haven't seen a SCSI card without onboard bios for years :-} In short, don't be too concerned.

My pc uses the same scsi controller to run the second drive. My bios loads because I left the default option to load ON . It reports it as loaded . this all takes place during system boot before any disk starts to boot-up. In fact if you have an ide drive and this scsi controller and a scsi drive in the same pc , it will not reliably boot from the scsi anyhow. The manual ( leaflet really ) you get with the card informs you of that . It also advises that if you do not enable the scsi adapter bios you cannot have these functions : send start multiple lun bootable cdrom ctrl-a displayed support for int13 In short be concerned .

Yup David is right, Unless you have scsi harddrives in you machine you do not need to enable the scsi bios, and if you machine is working fine, I would stay away from the bios updates... if it aint broken dont fix it.

I have a similar Error message. I installed SCSI controller on my computer and every time i boot, i get the error "SCSI Bios not instlled". My problem is serious because windows NT does not detect the CD Writter Drive. I have a another CD Drive installed on my computer and it is the only Drive i can see. Can anyone help me out on this?

Hi there, The same problem is present in my boot processing. I've a CD-RW Yamaha(SCSI3) and an Adaptec EZ-SCSI 5.0. I've also an DVD-rom but not SCSI. Adaptec EZ-SCSI = ID-SCSI 0 CD-RW YAMAHA = ID-SCSI 3 It's correct? I'm italian and I don't speak English very well, sorry. Thanks Francesco
