You can just flash you own SIL3221 card, easy peasy.
one might think that when someone is a philosopher, application programmer and inventor he should also be able to "flash a card".
but let me tell you that i have no idea where to buy such a card and how to flash it.^^
my currently only half-working sonnet card gives me headache, after even (s)ataman could not help me to fix it or find the cause, i have given up and removed it and atm i use the internals SSDs at the quicksilver´s IDE (100) bus. (at the cost of the two small IDE drives, which isnt a real problem)
my dream setup would be a solution around a
seritek 1v4. but even if seritek would answer emails and deliver me a second hand one: i am in europe and i would like to buy a second one as replacement part (for the next 20 years of professional OS9 use) and t wo cards wioth oversea shipping is almost a bit above my budget for that kind of stuff.
(...u think using that ATA card with adapters will be much slower? my SATA HDs once gave me 110mb/s via PCI and 92 via cheap adapter at the ATA 100...)
