Win98 can automatically detect the aha-1520 scsi card with corect device. Can you further the details of your problem.

Did you look at the Linux question I made reference to?  It would clarify what I am actually looking for and why I posted this question to the Win98 section.

Although Win98 does detect the card, it still reports (if you look  under the properties for the scsi card) that "the card has no knowledge of the settings being used..." (or something to that effect).  This may have something to do with this problem.

Studied yr problems stated in Linux page:
1)you can visit the website http://www.adaptec.com/support/overview/aha1520.html and see the page product to identify the AHA1520 scsi host adapter. You can download the 152X140.exe to updating your scsi card in order you can use the 140h port. the win152x.exe to unzip into program:
showscsi.exe and run win1520.exe so that you can config your 1520 card into proper IRQ. Base I/O and bios address.

Since AHA1520 with bios can be used to connect both internal scsi device such as bootable Hard disk and external scsi device.
If the bios is set enabled, the with IRQ12, port 140h, Mem DC0000h syscronized enabled, disconnected enabled, the scsi card can be bootable and it will be in conflict if you have bootable IDE harddisk and the card is not using internal scsi harddisk.

This conflict answered your question following:

I did as you suggested, however Win98 stopped seeing the card when I went to 0x140 and I started getting 'host adapter diagnosic errors" from the bios.  There are no new devices on the scsi bus from the old board to the new board.

Solve: using the download win1520.exe to disabled the bios setting and remember in the PC bootable bios in your motherboard , please Verify that Shadow RAM is not enabled in CMOS setup.

Moreover, for PCI cards, lower IRQ is used. For AHA1520, only 9,10,11,12 can be used for ISA card. Thus,try to configure those
PCI card to lower IRQ such as moving yr PCI soundcard to IRQ7.
Then configure the scsi card to use IRQ10 and see. But in my experience, the configuration autoconfigured by win98 with no conflict, please try to follow and not amending win98 but better to amend the scsi card setting.

Do not sure if you have network card such as NE2000 compatible that you may have configured to use Port340h, either try to use Port350 for your network card. and take 340h for scsi card.
Otherwise use Port140 with scsi-card bios disabled.

For dos, please check in the config.sys line as for port 140h:
Device=c:\scsi\aspi2dos.sys /D /P140
Device=c:\scsi\aspidisk.sys /D

For dos, please check in the config.sys line as for port 340h:
Device=c:\scsi\aspi2dos.sys /D /P340
You may updating the aspi2dos.sys and aspidisk.sys from the adaptec web page.

Hope that can give u some help. pslh
